# Moderate Time and Work Solved QuestionAptitude Discussion

 Q. Two taps can fill a tank in 12 min and 18 min respectively. Both the taps are kept open for 2 min and then the tap that fills the tank in 12 min is turned off. In how many more minutes will the tank be filled?
 ✖ A. 9 ✖ B. 12 ✔ C. 13 ✖ D. 10

Solution:
Option(C) is correct

In 2 minutes, the taps fill $2\left(\dfrac{1}{12}+\dfrac{1}{16}\right)$ or $\dfrac{5}{18}$of the tank.

Therefore, $\left(\dfrac{13}{18}\right)^{th}$of the tank is to be filled by the second tap at the rate of $\dfrac{1}{18}$ of the tank per minute.

This will take another 13 minutes.
