Question

If 12 men complete a piece of work in 10 days in how many days would 15 men complete the same work​

Answer 1

Explanation:

number of men =12

time taken = 10 days

time taken to complete the work by 15 men = 12÷10=1.2

= 1.2 ×15 = 18

therefore, 18 days is taken to complete the work by 15 men

Answer 2

12 men = (1/10) work per day

15 men = (1/8) work per day

So 8 days
