Question

In a hostel 1/3 of the total number of girls and four more take non-vegetarian food only, 1/4 and 3 more take vegetarian only. The other 103 take both veg and non veg. How many girls are there in the hostel.

Answer 1

let total girls be x
Non veg girls = 1/3x + 4
Veg girls= 1/4x + 3
Both veg and non veg =103
1/3x + 1/4x + 3 + 4 + 103 = x
110 = x - 1/3x - 1/4x
110 = 12/12x - 4/12x - 3/12x
110 = 5/12x
110 × 12/5 = x
22 × 12 = x
264 = x
there are 264 girls in the hostel
