Question

Pipes A and B can fill a tank in 5 & 6 hrs respectively and pipe C can empty it in 12 hrs . If the tank is half full and all the three pipes are in operation simultaneously then after how much time the tank will be full ? ( Give step by step explanation pls )​

Answer 1

Answer:

3.5 hours

Step-by-step explanation:

In one hour :

Tank Filled by A = 1/5

Tank Filled by B = 1/6

Tank Empty be C = 1/12

If three pipes are combined then tank filled in one hour =

1/5 + 1/6 - 1/12

= 17/60

17/60 of tanked filled in one hour.

So time taken to fill tank = 60/17 * 1

= 3.5 hours
