Solutions:
1. B) ? = 11.25 × 135 /100 + 8.72 × 463/100
= 15.1875 + 40.37 = 55
2. D) ? = 27 × 169 + 5317
= 4563 + 5317 = 9880
3. C) ? = 3 2/7 + 6 1/7 – 2 1/7 + 13 2/3
= (3 + 6 + 13 – 2) + ( 2/7 + 1/7 - 1/7 + 2/3) = 20 + (6 + 3 – 3 + 14)/21 = 20 + 20/21 = 21
4. E) ? = (63.5 × 8924.19)/100 +(22 × 5324.42)/100
= 63.5 × 89 + 22 × 53 = 5651 + 1166 = 6817
5. E) 134 × 3894 /100 + 38.94 × 134/100
= 134 × 3900/100 + 39 × 134/100 = 5226 + 52 = 5278 ≈ 5280
6. A) The series is a combination of two series:
Series I: 15 + 4 = 19; 19 + 4 = 23; 23 + 4 = 27
Series II: 16 + 2 = 18; 18 + 2 = 20; 20 + 2 = 22
7. D) The series is: +2, +2, +3, +3, +4, +4, ...
8. E) The series is: 27 + 32 = 59; 32 + 59 = 91; 59 + 91 = 150; 91 + 150 = 241; 150 + 241 = 391
9. B) The sequence of series is as follows
29 + 2 × 1 = 31, 31+ 3 × 2 = 37
37 + 4 × 3 = 49, 49 + 5 × 4 = 69
69 + 6 × 5 = 99
Or
Difference of series is = 2, 6, 12, 20, 30
Difference of difference = 4, 6, 8, 10, 12
10. C) The sequence of series is as follows.
26 × 1/2 − 1 = 12, 12 × 1− 1 = 11
11 × 3/2 − 1 = 15.5, 15.5 × 2 − 1 = 30
30 × 5/2 − 1 = 74
