Question 53

A carpenter can build a cupboard in 60 hours. After 15 hours he takes a break. What fraction of the cupboard is yet to be built?

Time taken to build the cupboard = 60 hours

Time spent = 15 hours

=> Fraction of the cupboard yet to be built = $$\frac{(60 - 15)}{60} = \frac{45}{60}$$

= $$\frac{3}{4} = 0.75$$

=> Ans - (C)
