**Q. An empty bottle weighs 1/6th of the full bottle. When a certain percent of water was removed and the bottle was weighed, the weight of the bottle turned out to be 1/3rd of the bottle when it was full. What is the percent of water removed?***- Published on 06 Jul 15***a.** 70%

**b.** 85%

**c.** 80%

**d.** 75%

**ANSWER: 80%**

Let the weight of full bottle be 6kg.

Therefore, weight of empty bottle is 1kg and that of water is 5kg.

If x% of water is removed, the weight of the bottle becomes 2kg.

Therefore, the amount of water removed is 4kg.

% of water removed = 4/5 *100 = 80%
