Answer provided by our tutors
let
a = the days that tap A needs to fill the pool
b = the days that tap B needs to fill the pool
1/a + 1/b = 1/15
A and B are kept open for 12 days and then B is closed It takes another 8 days for pool to be filled
12/15 + 8/a = 1
by solving for a we find
a = 40 days

1/40 + 1/b = 1/15
by solving for b we find
