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?
Answer & explanation
Correct answer: option 2
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
