Question 1

Directions: One number is missing in the series. You have to understand the pattern of the series and then insert the missing number.

45, 54, 47, ?, 49, 56, 51, 57, 53

 A

48

 B

55

 C

50

 D

50

Soln.
Ans: b

There are two alternate series in the single series, one of them moves with a sum of 2 starting with 45[see 45, 47, 49, 51, 53], and another is a consecutive series starting with 54. Hence, the missing number will be 55.


Question 2

11, 10, (?), 100, 1001, 1000, 10001.

 A

101.

 B

110.

 C

111.

 D

1101.

Soln.
Ans: a

There are two series: 11, 101, 1001, 10001, one zero is increased between two digits of 1 - 1. The second series is 10, 100, 1000, one zero is increased in the end.


Question 3

What is missing?

 A

131.

 B

118.5.

 C

129.

 D

105.5.

Soln.
Ans: a

The series is: 81 x 0.5 + 0.5 = 41, 41 x 1 + 1 = 42, 42 x 1.5 + 1.5 = 64.5, 64.5 x 2 + 2 = 131.

If you are still confused, 81 X 0.5 = 81 X 1/2 = 40.5, so 40.5 + 0.5 = 41.


Question 4

Directions: One number is missing in the series. You have to understand the pattern of the series and then insert the missing number.

2, 6, 12, 20, ?, 42, 56, 72, 90

 A

20

 B

21

 C

30

 D

12

Soln.
Ans: c

series moves with the increasing difference by 2 i.e., 4, 6, 8, 10, 12 . . . . . . Therefore, the missing number will be 30 .


Question 5

Which set of numbers is like given set 246, 257, 358?

 A

143, 253, 246.

 B

233, 343, 345.

 C

273, 365, 367.

 D

146, 235, 325.

Soln.
Ans: c

The numerology sums of all the three digits of the terms of the given set are 3, 5 and 7 because 2 + 4 + 6 = 12 → 1 + 2 → 3; 2 + 5 + 7 = 14 → 1 + 4 → 5 and 3 + 5 + 8 = 16 → 1 + 6 = → 7. Similarly sums of all these digits of each term of the set 273, 365, 367, 367 are 3, 5 and 7.
