If the ratio of male and female students specializing in B is 4 : 3 and that of male and female students specializing in D is 8 : 7, then the number of female students in D is what percent less than the number of male students in B (correct to one decimal place)?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 41.7
Number of people specializing in B = 75.6/360 × 2100 = 441.
The ratio of male and female students specializing in B is 4 : 3
Male student = 4/7 × 441 = 252
Female students = 441 - 252 = 189
Number of people specializing in D = 54/360 × 2100 = 315.
The ratio of male and female students specializing in D is 8 : 7
Male student = 8/15 × 315 = 168
Female student = 147
Required percentage = (252 - 147)/252 × 100 = 41.7%
