Question

Andrew can paint the neighbor's house 5 times as fast as Bailey. The year

Andrew and Bailey worked together, it took them 3 days. How long would it take
each to paint the house?

Answer 1

365 days

Explanation:

Let Andrew alone paint the house in

x days & Bailey alone paint the house in 5x days

Now, Andrew & Bailey together paint the same house in 6 days i.e. they together do 16 of painting work in a single day hence we have

1x+15x=16 65x=16x=365

Hence, Andrew alone can paint the house in x=365 days & Bailey alone can paint the house in 5x=36 days
