Question

if 5 men can paint the wall of a building in 16 days . In how many days will 20 men compleete the work​

Answer 1

Answer:

number of days 5 men need to paint the wall = 16 days

So number of days 1 man need to paint the wall = 16 * 5 days = 80 days

If 1 man need 80 days to paint the wall than 20 men need 80/20 days to paint the wall

therefore number of days 20 men need to paint

the wall = 80/20 = 4 days
