Answers:

1. 2;

Average number of candidates who passed from all institutes =(115 × 100)/7 ≅ 1640

2. 4;

3500-2000 = 1500

3. 3;

Required ratio = (20-10) : 35

= 10 : 35 = 2 : 7

4. 5;

Required difference = [(15 + 25 + 15 + 35) – (10 + 20 + 35)] × 100

= (90 – 65) × 100 = 2500

5. 2;

Required percentage [(15 + 20)/(15 + 40 )] × 100 = 35/55 × 100 = 64%

6. 3;

14 – 10 = 4

25 – 14 = 11 = 4 × 3 – 1

 55 – 25 = 30 = 11 × 3 – 3

140 – 55 = 85 = 30 × 3 – 5

? = 140 + 85 × 3 – 7

= 140 + 248 = 388

7. 5;

119 + 1 × 12 = 131

131 + 2 × 12 = 155

155 + 3 × 12 = 191

191 + 4 × 12 = 239

239 + 5 × 12 = 299

8. 4;

11 + 2 × 23 = 11 + 46 = 57

57 + 2 × 46 = 57 + 92 = 149

149 + 2 × 92 = 149 + 184 = 333

333 + 2 × 184 = 333 + 368 = 701

701 + 2 × 368 = 701 + 736 = 1437

9. 2;

697 – 553 = 144 = 12²

553 – 453 = 100 = 10²

453 – 389 = 64 = 8²

389 – 353 = 36 = 6²

 ? = 353 – 4² = 353 – 16 = 337

10. 1;

336 – 224 = 112

224 – 168 = 56

168 – 140 = 28

140 – 126 = 14

126 - ? = 7

? = 126 – 7 = 119
