Question 99

What portion of a 'Saree' can Rehana paint in 1 hour, if it requires 5 hours to paint the whole Saree? In 4$\frac{3}{5}$ hours? In 3$\frac{1}{2}hours$?

Answer 1

In 5 h, Rehana paints = whole saree
In 1 h, she paints $=\frac{1}{5}$ part of saree
In 4 $\frac{3}{5}$ h, she paints $=\frac{1}{5}\times \frac{(5\times 4)+3}{5}=\frac{1}{5}\times \frac{23}{5}=\frac{23}{25}$ part of saree
IN $3\frac{1}{2}$ h, she paints $=\frac{1}{5}\times 3\frac{1}{2}=\frac{1}{5}\times \frac{(3\times 2)+1}{2}=\frac{1}{5}\times \frac{7}{2}=\frac{7}{10}$ part of saree
