Question 53

Anil, Dinesh and Deepak together can complete a work in 40 days. Anil and Dinesh together can complete the same work in 50 days. In how many days Deepak alone can complete the same work?

Solution

Time taken by Anil, Dinesh and Deepak together to complete the work = 40 days

Time taken by Anil and Dinesh together = 50 days

=> Work done by Deepak alone = $$\frac{1}{40}-\frac{1}{50}$$

= $$\frac{5-4}{200}=\frac{1}{200}$$

$$\therefore$$ Time taken = 200 days

=> Ans - (B)
