Answer 1

5 painters can paint a house in 3 days.
So  1 painter can paint a full house in 3 * 5 = 15 days.

So   1 painter paints  1/15th part of of a house in  1 day.
So   3 painters  paint   3* 1/15 th part of a house in 1 day.
So   3 painters  will paint  3 * 1/15 * 4  th part of house in 4 days.
               So:   4/5 th part.
