(1) 27.5       (2) 32         (3) 28            (4) 30.5       (5) None of these

1. (1) 16945 × 125208 ÷ 516 + 79

= 659 + 79 = 729  = 8

1. (1) 38 of 168 × 15 ÷ 5 + ? = 549 ÷ 9 + 235

38 × 168 × 3 + ? = 61 + 235

189 + ? = 296

? = 296 – 189 = 107

? = 107 × 107 = 11449

1. (2) 1456 ÷ 16 × 14 + 22 =   (?)2

91 × 14 + 22 =    (?)2

1296 =    (?)2

(?)     = 36

1. (1) (0.64)4 ÷ (0.512)3 × (0.8)4 = (0.8)? + 3

(0.8)8 ÷  (0.8)9 ×  (0.8)4 =  (0.8)? + 3

? + 3 = 8 – 9 + 4

? + 3 = 3

? = 0

1. (1)  62 22 2 – (6)3 + 28

= 36 11 – 216 + 28 = 208 = 14.42

1. (2) The pattern of the number series is :

732 – 3 = 729 = 93

1244 – 732 = 512 = 83

1587 – 1244 = 343 = 73

1803 – 1587 = 216 = 63

1928 – 1803 = 125 = 53

? = 1928 + 43 = 1928 + 64 = 1992

1. (4) The pattern of the number series is :

16 × 1.5 = 24

24 × 2.5 = 60

60 × 3.5 = 210

210 × 4.5 = 945

1. (1) The pattern of the number series is :

(45030 5) – 6 = 9000

(9000 5) – 5 = 1795

(1795 5) – 4 = 355

(355 5) – 3 = 68

(68 5) – 2 = 13.6 – 2 = 11.6

1. (1) The pattern of the number series is :

5 × 1 + 1 × 7 = 12

12 × 2 + 2 × 6 = 36

36 × 3 + 3 × 5 = 123

123 × 4 + 4 × 4 = 492 + 16 = 508

508 × 5 + 5 × 3 = 2540 + 15 = 2555

1. (4) The pattern of the number series is :

8 × 0.5 + 7 = 4 + 7=11

11 × 1 + 6 = 17

17 × 1.5 + 5 = 25.5 + 5 = 30.5

30.5 × 2 + 4 = 61 + 4 = 65
