Question

A pump can fill a tank with water in 2 hours. because of a leak, it took 2 1 third hours to fill the tank. the leak can drain all the water of the tank in

Answer 1

 the total area of pump=1 part

The pump takes 2 hrs to fill 1 part 

The pump takes 1 hour to fill 1/2 portion 

 

Due to lickage  

The pump takes 7/3 hrs to fill 1 part 

The pump takes 1 hour to fill 3/7 portion 

Now the difference of area = (1/2-3/7)=1/14 

 

This 1/14 part of water drains in 1 hour 

Total area=1 part of water drains in (1x14/1)hours= 14 hours 

 

So the leak can drain all the water of the tank in 14 hours. 

Leak will empty the tank in 14 hrs
