Due to hole at the bottom of the tank, a tap takes 2 more minutes to completely fill the tank. Due to leakage of water through this hole, a bucket filled completely with water gets emptied in 4 minutes. In how much time can the tap fill the tank, if there was no hole at the bottom at the tank?


8 min


2 min


4 min


6 min

Option(B) is correct

Let the tap completely fill the tank (with no hole in it) in $x$ min

\(\Rightarrow \dfrac{1}{x}-\dfrac{1}{4}=\dfrac{1}{x+2}\)

$⇒ x$ = 2 minutes.

Is the capacity of bucket and tank are same ? Because different value of bucket capacity rate of per min water emptied will be different.
