Question

If 3/5 part of a work is done by 12 men in 10 days,
how many men will complete the whole work in 20
days?
168
10​

Answer 1

Work = no. of men × no. of days

3/5 = 12×10

3/5 = 120

3 = 600

200 units

hence 200 units of work done in 10 days by 12 men.

now, we have to find the no. of men complete the total work in 20 days.

so,

no of men = 200/20 = 10 men

hence, 10 men complete the whole work in 20 days.

Hope it helps.
