guys mera ans 2.20 pm aa raha hain
till 11 am 1st pipe fills 1/5 of the tank and second pipe fills 1/6 of the tank so till11 am 11/30 tank is filled, now if all pipes are opened simultaneously in 1 hr 1/ 10 of the tank gets emptied(1/15+1/12-1/4), so to empty 19/30 remaining portion they would need 19/30*10 hrs= 6 hrs and 20 min.so total time is 8+ 6 hrs and 20 min= 2.20 pm. Guys kindly point out where i made mistake
11+6hrs 20min hoga na!!
