Step-by-step explanation:

In 1 day, 12 men can complete 1/9 of work

In 6 days, 12 men will complete 6/9 = 2/3 of work

So, after 6 days the work left is 1/3

Therefore , 12 men can complete the 1/3 work in 3 days

So, 1 men will complete 1/3 of the work in 36 days

There 18 men (12+6) will complete the remaining work in 36/18 = 2 days
