Q. |
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? |

✖ A. |
8 min |

✔ B. |
2 min |

✖ C. |
4 min |

✖ D. |
6 min |

**Solution:**

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.
