A tank is filled by three pipes: Pipe A, Pipe B, and Pipe C. Working alone, Pipe A can fill the tank in 6 hours, Pipe B in 4 hours, and Pipe C in 3 hours. If all three pipes are opened together, but Pipe C is closed after 1 hour, how many hours in total will it take to fill the tank?

Can anyone send solution for this please

Let’s say capacity of tank is 12units
Then after an hour , 2+3+4=9 units is filled
Then let’s say after t hours rest of the tank will be filled. Now left over is 12-9=3 units

5t= 3
t=3/5
So total time=1+3/5=8/5

Ie 1hr 36mins

This is tricky .. since only 3 colours are available so we can’t have 4 different colours when picked up.
So there will be atleast two socks of a same colour. So probability is 1
