Cloth Makers Inc. has p spindles, each of which can produce q metres of cloth on an average in r minutes. If the spindles are made to run with no interruption, then how many hours will it take for 20,000 meters of cloth to be produced?

Solution

Time taken to make $$(pq)$$ metres of cloth = $$r$$ min

=> Time taken to make 20,000 m of cloth = $$\frac{r}{pq}\times20,000$$ minutes

$$\therefore$$ Required time (in hour) = $$20,000\times\frac{r}{60(pq)}$$

=> Ans - (D)
