Question

20 men can finish the construction of a wall in 16 days. How many more men are required to finish the work in 2 1/2 days?​

Answer 1

Answer:

Step-by-step explanation:

20 men can finish the wall in 16 days.

So to finish in one day, 20*16 = 320 men are required.

Now to finish in 2 1/2 days,

number of men required = 320 / (5/2)  = 128.

Thus more men required to finish in 2 1/2 days = 128 - 20 = 108.
