Question

Ramila paid 1/3 poja paid 1/5 what part swati paid

Answer 1

Let Amount paid by Swati be 'x'
1/3 + 1/5 + x = 1
5/15 + 3/15 + x = 1
8/15 + x = 1
x = 1 - 8/15
x = 15/15 - 8/15
x = 7/15
Swati paid 7/15 part.

Answer 2

The whole amount will be x
Amount Ramila paid = x/3
Amount Pooja paid = x/5

Amount Swati paid = x - x/3 - x/5
= 15x/15 - 5x/15 - 3x/15
= 7x/15

Swati paid 7/15
