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

Solution:

Time required by Rehana to paint one whole saree = 5 hours

In 1 hour she paints = 1/5th part of a saree.

In 4(3/5) hours she paints = 1/5 × 4(3/5) = 1/5 × 23/5 = 23/25 part of saree.

SImilarly in 3(1/2) hours she paints = 1/5 × 3(1/2)

= 1/5 × 7/2 = 7/10 part of saree.
