12 hr 1 unit= 12 capacity
so 4 part mean 3 each
now 3/4th the hight there is 4 tap with 1 unit each .
3/4+3/3+3/2+3/1= 75/12= 6 hr 15 min

Given that,
The first pipe is at the base of the tank. and the 4th pipe is at 3/4 th of height of the tank.
If the first pipe can empty the tank in 12 hours.
It means 12 hours one unit = 12 capacity
Four part means 3 each
We know that,
The fourth pipe is at th of height of the tank.
Now, the height there is fourth tap with 1 unit each.
So, time for third pipe
time for second pipe
time for first pipe
We need to calculate the time
Using formula for time
Put the value into the formula
Hence, The tank will empty in 6 hours 25 min.
