alphanumeric series Model Questions & Answers, Practice Test for ibps clerk prelims

Answer: (a)

The series is based on following pattern:

8 × 1 – 2 = 6

6 × 2 – 3 = 9

9 × 3 – 4 = 23

23 × 4 – 5 = 87

87 × 5 – 6 = 429

Similarly, the new series is as follows:

6 × 1 – 2 = 4 .... (1)

4 × 2 – 3 = 5 .... (2)

5 × 3 - 4 = 11 ..... (3)

11 × 4 – 5 = 39 .... (4)

39 × 5 – 6 = 189 .... (5)

Therefore, the number 11 will come in place of (3)

Answer: (a)

The series is based on the following pattern:

5 × 1 + 2 = 7

7 × 2 – 4 = 10

10 × 3 + 6 = 36

36 × 4 – 8 = 136

136 × 5 + 10 = 690

Similarly, the new series is as follows:

2 × 1 + 2 = 4 .... (1)

4 × 2 – 4 = 4 .... (2)

4 × 3 + 6 = 18 .... (3)

18 × 4 – 8 = 64 .... (4)

64 × 5 + 10 = 330 ....(5)

Therefore, the number 330 will come in place of (5).
