p1+p1=18 litre/min

leak pipeworks = 1/10 per min

tank filled in 15min , totalworkratepermin =1/15

(inletwork - leakagework)=totalworkratepermin

inlet work rate=totalworkratepermin + leakage work =(1/15)+(1/10)=1/6

therefore, inlet pipe fill at the rate (1/6)per min.i.e tank is filled in 6 min

speed of both inlet given=18litrepermin

Capacity of tank=6*18=108 liters.
