IBPS Clerk Aptitude Free Mock Test – Prelims Exam
1. A student multiplied a number by 3/5 instead of 5/3, What is the percentage error in the calculation?
A. 54 %
B. 64 %
C. 74 %
D. 84 %
Answer – B. 64 %
Explanation:
Let us assume that the number be x.
Then, ideally, he should have multiplied by x by 5/3. Hence Correct result was x * (5/3)= 5x/3.
By mistake he multiplied x by 3/5 . Hence the result with error = 3x/5
Then, error = (5x/3 – 3x/5) = 16x/15
Hence, Error % = (error/True vaue) * 100 = [(16/15) * x/(5/3) * x] * 100 = 64 %
2. Vamsi spends 30% of his monthly income on food articles, 40% of the remaining on conveyance and clothes and saves 50% of the remaining. If his monthly salary is Rs. 18,400, how much money does he save every month ?
A. 3864
B. 4903
C. 5849
D. 6789
Answer – A. 3864
Explanation:
Saving = 50% of (100 – 40)% of (100 – 30)% of Rs. 18,400 = Rs. (50/100 * 60/100 * 70/100 * 18400) = Rs. 3864.
3. A man spends 10% of his income in house rent, 20% of the rest on his children’s education, 25% of the rest miscellaneous causes. If he now posses Rs. 1944 then his income is?
A. Rs.3600
B. Rs.4000
C. Rs.4500
D. Rs.3000
Answer – A. Rs.3600
Explanation:
Let us assume the required income of the man is ‘x’
Then, x * (90/100) * (80/100) * (75/100) = 1944
x * 0.9 * 0.8 * 0.75
x = 1944/0.54
x = 3600
Therefore, the income of the man is Rs.3600.
4. In a school of 850 boys, 44% of Muslims, 28% Hindus, 10% Sikhs and the remaining of other communities. How many belonged to the other communities?
A. 151
B. 152
C. 153
D. 154
Answer – C. 153
Explanation:
According to the given information, the total percentage is
44 + 28 + 10 = 82%
Then, the remaining percentage is 100 – 82 = 18%
Now, 850 * 18/100 = 153
Therefore, the boys who are belonged to other communities are 153 members.
5. When the numerator of a fraction is decreased by 25% and its denominator is decreased by 20%, the new fraction obtained is 3/4. Find the original fraction?
A. 4/5
B. 5/4
C. 5/6
D. 6/7
Answer – A. 4/5
Explanation:
Let us assume, the fraction is x/y.
When the numerator decreased by 25% and the denominator decreased by 20%.
Then, (x * 3/4)/(y * 4/5) = 3/4
=> x/y = 3/4 * (4/5)/(3/4) = 4/5
6. 4 men and 6 women can complete a work in 8 days, while 3 men and 7 women can complete it in 10 days. In how many days will 20 women complete it?
A. 10 days
B. 15 days
C. 20 days
D. 25 days
Answer – C. 20 days
Explanation:
Let us assume
1 man’s 1 day’s work = x days
1 woman’s 1 day’s work = y
Then, 4x+6y = 1/8 and 3x+7y = 1/10.
Solving these two equations y = 1/400
1 woman’s 1 day’s work = 1/400
Therefore, 20 women = 20/400 = 1/20 = 20 days.
7. X can do a piece of work in 20 days. Y, in 15 days X and Z in 12 days. In how many days can X finish the work if he is assisted by Y on one day and Z on the next, alternately?
A. 10
B. 8
C. 6
D. 4
Answer – B. 8
Explanation:
X + Y = 1/20 + 1/15 = 7/60
X + Z = 1/20 + 1/12 = 8/60
7/60 + 8/60 = 15/60 = 1/4
4 days * 2 = 8 days
Hence, X finish the work if he is assisted by Y on one day and Z on the next day is 8 days
8. P and Q can do work in 5 days and 10 days respectively. P starts the work and Q joins him after 2 days. In how many days can they complete the remaining work?
A. 1 day
B. 2 days
C. 3 days
D. 4 days
Answer – B. 2 days
Explanation:
Work is done by P, in 2 days = 2/5
Remaining work = 3/5
Work done by both P and Q in one day = 1/5 + 1/10 = 3/10
Therefore, Remaining work = 3/5 * 10/3 = 2 days.
9. Praveen can read a book in k minutes. What part of the book can be read in 8 minutes?
A. 4/k
B. 6/k
C. 8/k
D. 16/k
Answer – C. 8/k
Explanation:

Part of the book Praveen can read in 1 minute = 1/k
Similarly, Part of the book Praveen can read in 8 minutes =8/k.
10. Vineeth and Gopinath can complete a work in 10 days and 15 days respectively. Gopinath starts the work and after 5 days Vineeth also joins him in all the work would be completed in?
A. 9 days
B. 10 days
C. 11 days
D. 12 days
Answer – A. 9 days
Explanation:
Gopinath’s 5 day’s work = 5 x 1/15 = 1/3
Remaining work = (1 – 1/3) = 2/3 (1/10 +1/ 15) work is done by both in 1 day
Therefore 2/3 work is done by both in (6 x 2/3) = 4 days.
Hence, The work was completed in 9 days
11. A piece of work has to be completed in 50 days, a number of men are employed but it is found that only half of the work is done in 30 days, then an additional 20 men were joined to complete the work on time. How many men initially put to work?
A. 30
B. 35
C. 40
D. 45
Answer – C. 40
Explanation:
Suppose, let us assume
Initially, x men get employed.
Then, Half work is done in 30 days it means full work will be done by x men in 60 days.
Now, Work done = 1/2 = [20*(x + 20)]/60x
By solving you will get x = 40
Therefore, the number of men initially put the work are 40.
12. Eight years ago, M was 4 times as old as N. After 8 years M will be twice as old as N. What are their ages respectively?
A. 40, 10
B. 40, 16
C. 42, 18
D. 45, 18
Answer – B. 40, 16
Explanation:
Let N’s age 8 yrs ago = x, then M’s age = 4x
After (8+8) = 16 years:
(4x+16) = 2 * (x+8)
Solve, x = 8
M’s present age = 4x+8 = 40
N’s present age = x+8 = 16
13. Age of A is three times the sum of ages of B and C. 5 years hence, A’s age will be twice the sum of ages of B and C. The total of their present ages is
A. 45 years
B. 50 years
C. 55 years
D. 60 years
Answer – D. 60 years
Explanation:
Let (B+C)’s present age= x
Then A’s present age = 3x
After 5 years, (3x+5) = 2*(x+5+5)
Solve, x = 15
Sum = x+3x = 4x = 60
Therefore, the total of their present ages is 60 years.

B. 16 min 40 sec.
C. 13 min 10 sec.
D. 14 min 40 sec.
Answer – D. 14 min 40 sec.
Explanation:
Part filled in 4 minutes = 4(1/15 + 1/20) = 7/15
Remaining part = 1 – 7/15 = 8/15
Part filled by B in 1 minute = 1/20
1/20 : 8/15 :: 1 : k
k = (8/15 )x 1 x 20 = 10( 2/3) min = 10 min 40 sec.
Therefore, The tank will be full in (4 min. + 10 min. 40 sec) = 14 min 40 sec.
19. One fill pipe A is 3 times faster than second fill pipe B and takes 32 minutes less than the fill pipe B. When will the cistern be full if both pipes are opened together?
A. 6 min
B. 8 min
C. 12 min
D. 10 min
Answer – C. 12 min
Explanation:
Let pipe A takes p min to fill
Then, pipe B takes a 3p min to fill
=> 3p – p = 32
=> p = 16 min
Then, 3p = 48 min.
Hence, Required, both pipes to fill = (48 x 16)/(48 + 16) min = 12 min.
20. The average of runs of a cricket player of 10 innings was 32. How many runs must he make in his next innings so as to increase his average of runs by 4?
A. 76
B. 79
C. 85

7. A train 350 m long takes 36 seconds to cross a man running at a speed of 5 km/h in the direction opposite to that of train. What is the speed of the train?
a) 30 km/h
b) 40 km/h
c) 24 km/h
d) 34 km/h
e) Other than those given as options
Answer (A)
Explanation:
Let the speed of the train be x m/s
Speed of the man = 5km/hr = 1.388m/s
Relative speed of man when he is running in opposite direction = (x+1.388)
However train crossess him in 36 seconds = 350/36 = 9.722 m/s
x+1.388 = 9.722
x = 8.334 m/s
x = 30 km/hr

Answer (C)
Explanation:
CP = (100×SP)/((100+gain%))=(100×84)/120= Rs. 70
9. Raj sold an item for Rs. 6384 and incurred a loss of 30%. At what price should he have sold the item to have gained a profit of 30%?
A. Rs. 14656
B. Rs. 11856
C. Rs. 13544
D. Cannot be determined
E.None of these
Answer (B)
Explanation:
Let the CP of the article be x.
Loss % = (CP-SP)/CP = (x-6384)/x = 0.3
1 – 6384/x = 0.3
x = 9120
Profit % = (SP-CP)/CP
0.3 = (SP-9120)/9120
SP = 9120*1.3 = Rs 11,856
10. Profit earned by the organisation is distributed among officers and clerks in the ratio of 5:3 If the number of officers is 45 and the number of clerks is 80 and the amount received by each officer is rs 25,000 what was the total amount of profit earned?
A. Rs. 22 lakh
B. Rs. 18.25 lakh
C. Rs. 18 lakh
D. Rs. 23.25 lakh
E. None of these
Answer (C)
Explanation
The total amount distributed among officers = 45*25000= 11,25,000
If the total amount is x, then this amount is (5/8)x=11,25,000
Hence, x=18,00,000
11. The cost price of an article is Rs. 480. If it is to be sold at a profit of 6.25 percent, what would its selling price be?
A. Rs. 510
B. Rs. 530
C. Rs. 503
D. Rs. 519
E. None of these
Answer (A)
Explanation
The selling price of the article is, Selling price = Cost Price + Selling price * (Percent Profit/100)
Selling Price = 480 + (6.25/100)*480 = 510
Hence, the correct option is option A.
12. The profit earned after selling an article for Rs 996 is the same as the loss incurred after selling the article for Rs 894. What is the cost price of the article ?
A. Rs 935
B. Rs 905
C. Rs 945
D. Rs 975
E. None of these
Answer (C)
Explanation
Let the CP be the Cost Price and SP be Selling Price.
Profit = SP – CP = 996 – CP
Loss = CP -SP = CP – 894
Now as Profit = Loss
2*CP = 1890
CP =945
Hence, the cost price is 945.
13. The ages of Nishi and Vinnee are in the ratio of 6:5 After 9 years the ratio of their ages will be 9:8 What is the difference in their ages?
a) 9 years
b) 7 years
c) 5 years
d) 3 years
e) None of these
Answer (D)
Explanation
Let the ages of Nishi and Vinnee be x and y.
Now, as per given conditions,
(x/y) = (6/5) i.e 5x=6y
after 9 years,
(x+9)/(y+9) = 9/8 i.e 8x-9y=9
After solving we get x = 18 and y = 15.
Differences in the ages = 18-15=3
Hence, option D is correct.

a) 3478
b) 1418
c) 5673
d) 2147
e)1077
Answer (E)
Explanation
9070 – 15^3 = 5675 , 5675 – 13^3 = 3478 , 3478 – 11^3 = 2147 , 2147 – 9^3 = 1418 , 1418 – 7^3 = 1075 ≠ 1077 , 1075 – 5^3 = 950
15. Study the following table carefully to answer the question that follows:
Question 1:
What is the ratio of the total number of candidates clearing the entrance exam from State B in the year 2004 to that of those clearing the entrance exam from State C in the same year?
a) 221:148
b) 218:143
c) 148:221
d) 143:218
e) None of these
Answer (A)
Explanation
Total number of candidates that cleared the exam in 2004 from State B = Total candidates that appeared * percentage cleared = 1.04 lakhs* 51% = 53,040
Total number of candidates that cleared the exam in 2004 from State C = 1.11 lakhs * 32% = 35,520
So, the ratio = 53,040 : 35, 520 = 221:148
Question 2:
In which year did the highest number of candidates clear the entrance exam from state D ?
a) 2008
b) 2006
c) 2009
d) 2007
e) None of these
Answer (C)
Explanation
The number of candidates clearing the exam = number of candidates appearing for the exam * percentage clearing the exam.
For the number of cleared candidates to be high, the number of candidates appearing should be high as well as the percentage clearing the exam as well.
We can observe that both these numbers are considerably high for 2009. We can calculate to find out that 2009 has the highest number of candidates that cleared the exam.
The number of candidates clearing the exam in 2009 = 2.01 lakhs * 56% = 1,12,560
Question 3:
What is the number of candidates not clearing the entrance exam from State A in the year 2007 ?
a) 186820
b) 11682
c) 1868200
d) 116820
e) None of these
Answer (D)
Explanation
Number of candidates appearing for the exam from A in 2007 = 1.98 lakhs
Percentage cleared = 41%
Percentage failed to clear = 1- 41%= 59%
So, number that failed to clear 1.98 lakhs * 59% = 1,16,820
Question 4:
What is the total number of candidates clearing the entrance exam from states E and F together in the year 2006?
a) 16160
b) 110660
c) 1.1066
d) 1106600
e) None of these
Answer (B)
Explanation
Number of candidates clearing the exam in 2006 from E = Number of candidates appearing * percentage that cleared = 1.42 lakhs * 49% = 69,580
Number of candidates clearing the exam in 2006 from F = 1.58 lakhs * 26% = 41,080
Total = 69, 580 + 41, 080 = 1,10,660
Question 5:
What is the average number of candidates appearing for the entrance exam from state D in the years 2007,2008 and 2009 together ?
a) $$1907\frac{2}{3}$$

18. Instructions: Each Of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and—
Give answer a: if the data in statement I alone are sufficient to answer the
the question, while the data in statement 11 alone are not sufficient to answer the question.
Give answer b: if the data in statement II alone are sufficient to answer the
the question, while the data in statement I alone are not sufficient to answer the question.
Give answer c: if the data either in statement I alone or in statement II alone are sufficient to answer the question.
Give answer d: if the data given in both the statements I & II together are not sufficient to answer the question. and
Give answer e: if the data in both the statements I & II together are necessary to answer the question
Question 1:
Who among M, N, P, T and R is the youngest?
I. N and T are younger than P.
II. M is older than R and P.
a) if the data in statement I alone are sufficient to answer the question, while the data in statement 11 alone are not sufficient to answer the question.
b) if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
c) if the data either in statement I alone or in statement II alone are sufficient to answer the question.
d) if the data given in both the statements I & II together are not sufficient to answer the question.
e) if the data in both the statements I & II together are necessary to answer the question
Answer (D)
Explanation
Clearly, I alone and II alone are insufficient as there is not sufficient data in each of these statements.
I & II : From the first statement, we get : P > N, T
From the second, we get : M > R, P
Combining the above two, we get : M > R, P > N, T
The youngest can be either N or T.
Thus, I & II together are not sufficient.
Question 2: How many children are there in the row ?
I. Manoj is twelfth from the left end and fourth to the left of Hari in that row.
II. Hari is eighth from the right end of that row.
a) if the data in statement I alone are sufficient to answer the question, while the data in statement 11 alone are not sufficient to answer the question.
b) if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
c) if the data either in statement I alone or in statement II alone are sufficient to answer the question.
d) if the data given in both the statements I & II together are not sufficient to answer the question.
e) if the data in both the statements I & II together are necessary to answer the question
Answer (e)
Explanation
NOTE :- Position from left end + Position from right end = Total students + 1
I : Manoj is 12th from left end and 4th to the left of Hari.
=> Hari’s position from left end = 12+4 = 16th
We did not know the total no. of students from this.
Thus, I alone is not sufficient.
II : Hari’s position from right end = 8th
We did not know the total no. of students from this.
Thus, II alone is not sufficient.
I & II : Combining the above two conditions, we get
Hari’s position from left = 16th and from right = 8th
=> Total students = 16+8-1 = 23
Thus, I & II together are sufficient.
Question 3: How is ‘red’ written in a code language ?
I. ‘red and blue’ is written as ‘ho po da’ in that code language.
II. ‘spread red carpet’ is written as ‘na da ka’ in that code language.

b) if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
c) if the data either in statement I alone or in statement II alone are sufficient to answer the question.
d) if the data given in both the statements I & II together are not sufficient to answer the question.
e) if the data in both the statements I & II together are necessary to answer the question
Answer (e)
Explanation
Clearly, I alone and II alone are insufficient.
Combining I & II together, the common word in both statements is red coded as ‘da’
Thus, I & II together are sufficient.

b) if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
c) if the data either in statement I alone or in statement II alone are sufficient to answer the question.
d) if the data given in both the statements I & II together are not sufficient to answer the question.
e) if the data in both the statements I & II together are necessary to answer the question
Answer (c)
Explanation
I: Village M is to the West of Village T which is to the South of Village R.
=> M is to the south west of village R, => R is to the north-east of village M.
Thus, I alone is sufficient.
II: Village M is to the South of Village B which is to the West of Village R.
=> M is to the southwest of village R, => R is to the north-east of village M.
Thus, II alone is sufficient.
Question 5: How many sisters does D have?

a) if the data in statement I alone are sufficient to answer the question, while the data in statement 11 alone are not sufficient to answer the question.
b) if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
c) if the data either in statement I alone or in statement II alone are sufficient to answer the question.
d) if the data given in both the statements I & II together are not sufficient to answer the question.
e) if the data in both the statements I & II together are necessary to answer the question
Answer (d)
Explanation
I : D’s mother has 4 children, which means that D has 3 siblings, of whom we do not know the gender of.
Thus, I alone is not sufficient.
II : There is no data related to D.
Thus, II alone is not sufficient.
I & II : Even after combining the two statements, we just know that D has 3 siblings, and we can’t determine the relation between ‘K,T,E’ and ‘D’.
Thus, I & II together are not sufficient.
19. Swati walks 150 m every day. How many kilometers will she walk in three weeks?
a) 2.04
b) 5.92
c) 4.18
d) 3.15
e) None of these
Answers (D)
Explanation
The number of days in 3 weeks is 3*7 = 21
Swati walks 150 meters every day.
Hence, the distance covered by Swati in 3 weeks equals 150*21 = 3150 meters
1000 meters equal one kilometer. Hence, the distance covered by Swati in 3 weeks is 3.15 km.
20. A boat running downstream covers a distance of 16 km in 2 hours while for covering the same distance upstream it takes 4 hours. What is the speed of the boat in still water?
a) 4 kmph
b) 6 kmph
c) 8 kmph
d) Data inadequate
e) None of these
Answers (B)
Explanation
Let the speed of the boat in still water be B and the speed of the water be W.
So, speed of the boat downstream is B+W and the speed of the boat upstream is B-W.
From the information given, the speed of the boat downstream is 16/2 = 8 kmph
Speed of the boat upstream is 16/4 = 4 kmph
Hence, B+W = 8 and B-W =4
So, B = 6 kmph and W = 2 kmph
21. Two cars A and B are running in the same direction. Car ‘A’ had already covered a distance of 60 kms, when car ‘B’ started running. The cars meet each other in 3 hours after car ‘B’ started running. What was the speed of car ‘A’?
a) 40 kmph
b) 60 kmph
c) 45 kmph
d) Cannot be determined
e) None of these
Answers (D)
Explanation
Let the speed of car A be ‘x’ kmph and the speed of car B be ‘y’ kmph.
By the time car B started running, car A covered 60 Km.
Distance covered by B in three hours is 3y
Distance covered by A in three hours is 3x
So, 3y = 3x + 60 or y=x+20
Hence, the speed of B is 20 kmph more than the speed of A. As we don’t know the speed of car B, we can’t find the exact speed of car A. We can just infer that the speed of car A is 20 kmph less than the speed of car B.

36. An alloy contains iron, copper, and zinc in the ratio of 3:4:2. Another alloy contains copper, zinc, and tin in the ratio of 10:5:3. If equal quantities of both alloys are melted, then the weight of tin per kg in the new alloy
a) 1/8 kg
b) 1/10 kg
c) 1/12 kg
d) 1/14 kg
e) None of these
Answer (C)
Explanation
I:C:Z = 3:4:2 (in first alloy) and C:Z:T = 10:5:3
Equal quantities are taken. So, I:C:Z = 6:8:4 in first alloy and C:Z:T = 10:5:3
I = 6
C = 8 + 10 = 18
Z = 4+5 = 9
T = 3
So weight of tin = 3/36 = 1/12

50. The perimeter of a rectangular field is 120 m and the difference between its two adjacent sides is 30 m. The sides of the square field whose area is equal to this rectangular field is?
A. 15√2
B. 12√2
C. 15√3
D. 12√3
E. None of the Above
Answer (C)
Explanation
Perimeter of rectangle = 2(l + b) = 120
l + b = 60m — (1)
l – b = 30m –(2)
From (1) and (2)
l = 45 m; b = 15m
Area of rectangle = 675m² = Area of Square
Side of a square = 15√3
