Study the following pie-chart and answer the following questions.

Total number of students in a college in various fields = 5000

Distribution of the number of students int various fields:

The ratio of the number of girls in economics to the number of students in economics is?

14 : 25

In Economics :

No. of students = 12% of 5000

No. of girls = 56% of (12% of 5000)

Therefore,

No. of girls : Total students =  56% of (12% of 5000) : (12% of 5000) = 56% : 1 = 56 : 100 = 14 : 25

Alternate:

Total students of Economics = 12%

12% of 5000 = 600

No. of girls = 56% of 600 = 336

Required ratio →

336 : 600

 14  :  25
