Answers :

1) Answer: B

Number of boys in school T = 2400 × 14/100 = 336

Ratio between number of boys to number of girls in school “T” = 7: 8

Number of girls in school T = 7x = 8 × 336

Number of girls in school T = 384

2) Answer: D

Required percentage = (20 - 14)/14 * 100

= 6/14 * 100

= 300/7 = 42 (6/7)% more

3) Answer: A

Average number of boys in school Q, R and S = (9 + 15 + 24)/3 = 16%

= 16/100 * 2400 = 384

4) Answer: E

Required angle = x * 100 = 18 * 360

Required angle = 64.8⁰

5) Answer: B

Total number of boys in school “P” = 20/100 * 2400 = 480

Total number of boys in school “Q” = 9/100 * 2400 = 216

Difference = 480 - 216 = 264
