Step-by-step explanation:
if 7 taps at same speed can fill a tank in 80 minutes then 1 tap will take 80 × 7 = 560minutes. 3 taps stop working so left taps are 4. 560/4 =140 minutes. 4 taps will fill the tank at same speed in 140 minutes. this is the answer if all the taps were running at same speed(for eg 20) and are still at same speed (20). if you are asking the question that their speed is increased and they take the same time as before the speed will be 320
