Question

20 men can do a piece of work in 24 days. After working for six days an additional number of men is employed to finish the work in 21 days from the beginning. Find the number of additional men. [3]​

Answer 1

Step-by-step explanation:

If the work to be done in 21 days then we have (21-6) = 15 days left to do the work with additional men. Let us say we have x number of additional men. So the amount of men in the team is (20+x). They need to do 360P work in 15 days.
