Question

if 3 taps are opened together a tank is filled in 3 hours.One of the tap above can fill it in 10 hours and another in 15 hours.in how many hours will the third tap fill it​

Answer 1

Answer:

6 hours

Step-by-step explanation:

Time taken by three taps to fill a tank = 3 hours

Work done by three taps in 1 hour = 1/3

Work done by one tap in 1 hour = 1/10

Work done by second tap in 1 hour = 1/15

Work done by both taps in 1 hour = 1/10 + 1/15 = 5/30 = 1/6

Work done by third tap in 1 hour = 1/3 - 1/6 = 1/6

Hence, the third tap will fill the tank alone in 6 hours.
