36 (a) (b) (c) (d) (e)
Out of the following numbers which would come in place of (e)?
A. 810
B. 36
C. 54
D. 108
Answer: A
Explanation:
The series is * 1; * 1.5; * 2 and so on, therefore:
(a) = 36 X 1 36
(b) = 36 x 1.5 = 54
(c) = 54 X 2 = 108
(d) = 108 X 2.5 = 270
(e) = 270 X 3 = 810
19. Find the wrong number in the series, and then find the third number in the new series?
3, 5, 12, 38, 154, 914, 4634
A. 1636
B. 1222
C. 1834
D. 3312
Answer: C
Explanation:
The series is X * 1 + 2,
X * 1 + 2 i.e., 3 * 1 + 2 = 5,
X * 2 + 2 i.e., 5 * 2 + 2 = 12,
X * 3 + 2 i.e., 12 * 3 + 2 = 38
X * 4 + 2 i.e., 38 * 4 + 2 = 154
X * 5 + 2 i.e., 154 * 5 + 2 = 772
So, 914 is the wrong number.
Now, starting from 914
Second number = 914 X 1 + 2 = 916
Third number = 916 X 2 + 2 = 1834
Therefore the third number in the new series is 1834.
20. Find out the missing number in the following sequence.
53, 44, 52,?, 51, 46.
A. 45
B. 61
C. 44

In the second sequence, each digit is increased by 1
44, 45, 46
Therefore 45 is the missing number.
