Question

A pipe can fill a tank in 12 hours and another pipe in 8 hours both pipes are opened for 5/2 then find the filled part of the tank is

Answer 1

Answer:

25/48 parts

Step-by-step explanation:

Let it be pipes A and B

A's 1 hr Work = 1/12

B's 1 hr Work = 1/8

So, (A+B)'s 1 hr work = (1/12) + (1/8) = 5/24

Now A and B is opened for (5/2) hrs

So, (A+B)'s (5/2) hrs Work = (5/24) * (5/2)

                                           = 25/48

So, After (5/2) hrs (25/48) part of the tank will be filled by both the pipes.
