Question

Thirty-six men can paint a wall in 18 days. In how
many days will 18 men complete the same work?​

Answer 1

Answer:

Let the rate of work of a man be 1 unit/ day.

So, total work = 36 * 18 = 648 units.

Now, 18 men will do 18 *1 units per day.

Total time taken = 648 / 18 = 36 days

Ans = 36 days
