Question 143

40 men can finish a work in 15 days. If the work is to be completed 3 days earlier, how many more people should be employed ?

Solution

40 men can finish a work in 15 days

Let $$x$$ men finish the work in (15 - 3) = 12 days

=> $$40 \times 15 = x \times 12$$

=> $$x = \frac{40 * 15}{12}$$

=> $$x = 50$$

$$\therefore$$ (50 - 40) = 10 more men are required.
