Solutions

S1. Ans.(e)

Sol. 17 + 8 = 25

8 + 25 = 33

25 + 33 = 58

33 + 58 = 91

58 + 91 = 149

So, ?=8

S2. Ans. (c)

Sol.

The series is set of alternate prime numbers.

7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53

S3. Ans.(a)

Sol. The pattern is

0 + 8 × 1 = 8

8 + 8 × 3 = 32

32 + 8 × 5 = 72

72 + 8 × 7 = 128

128 + 8 × 9 = 200

S4. Ans. (e)

S5. Ans. (d)

S6. Ans(e)

Sol.

Wrong number = 158

So, there should be 148 in the place of 158

S7. Ans(c)

Sol.

Wrong number = 148

Pattern of series –

122 + 16 = 138

138 – 20 = 118

118 + 24 = 142

142 – 28 = 114

114 + 32 = 146

So, there should be 146 in the place of 148.

S8. Ans(a)

Sol.

Wrong number = 254

Pattern of series –

8, 9, 20, 63, 256, 1285

So, 256 should come in the place of 254.

S9. Ans(a)

Wrong number = 92

90 should come in the place of 92.

S10. Ans.(e)

Sol.

Wrong number is 24.

22 should come in the place of 24.

S11. Ans.(d)

Sol.

S12. Ans.(e)

Sol.

12 × 1 + 1 = 13

13 × 2 +2 = 28

28 × 3 + 3 = 87

87 × 4 + 4 = 352

352 × 5 + 5= 1765

S13. Ans.(c)

Sol.

S14. Ans.(a)

Sol.

11 + 7 = 18

7 + 18 = 25

18 + 25 = 43

25 + 43 = 68

43 + 68 = 111

S15. Ans.(e)

Sol.

S16. Ans.(b)

Sol.

800 – 256 = 544,

544 -128 = 416,

416 – 64 = 352,

352 – 32 = 320,

320 – 16 = 304

S17. Ans.(d)

S18. Ans.(a)

Sol.

S19. Ans.(d)

Sol.

S20. Ans.(c)

Sol. The Series is

×1.5, ×2, ×2.5, ×3, ×3.5, ×4

So, 315 × 4 = 1260
