Question

What portion of a ‘saree’ can Rehana paint in 1 hour if it requires 5 hours to paint the whole saree? In 4 3/5 hours? In 3 1/2 hours?

Answer 1

Let total portion of saree be represented by 1.

The portion of saree painted by Rehana in 5 hours = 1.

∴ The portion of saree painted by her in 1 hour = 1/5

The portion of Saree painted by her in

4 3/5 hours = 1/5 x 4 3/5 = 1/5 x 23/5 = 23/25

The portion of saree painted by her in

3 1/2 hours = 1/5 x 3 1/2 = 1/5 x 7/2 = 7/10
