Number of days Jan will take to complete painting work alone is 40 days and Claudia will alone take 10 days to paint complete house.
<u>Solution:</u>
Given that
Claudia can paint a house four times as fast as Jan can.
let’s assume house painted by Jan in one day = x
So house painted by Claudia in 1 day = 4x
House painted by Jan in 8 days = 8 x house painted by Jan in 1 day = 8x
House painted by Claudia in 8 days = 8 x house painted by Claudia in 1 day = 8 4x = 32x
As painting is completed in 8 days , so complete work of painting = House painted by Jan in 8 days + House painted by Claudia in 8 days = 8x + 32x = 40x
So 40x represent complete work of painting house.
Work of painting done by Jan in 1 day = x
if Jan alone do the work, number of days required by Jan
Work of painting done by Claudia in 1 day = 4x
If Claudia alone do the work, number of days required by Claudia
Hence number of days Jan will take to complete painting work alone is 40 days and Claudia will alone take 10 days to paint complete house.
