# How Much More Time is Fill The Water Tank Completely?

If 2/5 portion of a water tank is filled up in 2 minutes, then how much more time is required to fill the water tank completely?

- 12 minutes
- 3 minutes
- 6 minutes
- 15 minutes

**Answer: (2) 3 minutes**

**Explanation:-
**Let the time by a tap to fill the tank = X min.

If 2/3 portion of a water tank is filled up in 2 minutes,

Then, X x 2/5 = 2

2 X = 2 x 5

X = 2 x 5/2

X = 5

Then, total time taken by a tap to fill the tank = 5

Then, the more time = 5- 2 = 3 min

Hence, the answer is (2) 3 minutes.
