A pump can fill a tank in 2 hours
so, A = 2
A's total work in one hour, A = 1/2
Because of a leak , it took 2*(1/3) hours to fill the tank
let leak be L
so, A-L=7/3 hours
total work in one hour,
A-L = 3/7
1/2-L=3/7
1/2-3/7 = L
(7-6)/14 = L
L = 1/14
in one hour the leak is L = 1/14
so total leak is L = 14 hours
