Question

If 300men can do a piece of work in 16days,how many men would do 1/5 of the work in 15days?
​

Answer 1

60men

Explanation:

300 men - 15 days - 1 work

men? - 15 days - 1/5 of work

When 1 man does 1/5 of work,

how many days needed = (15 × 1/5) × 300 = 900days

Men needed to complete 1/5 work in 15 days = 900 ÷ 15 = 60men
