A container is 1/6 full of orange juice. When 2 litres of orange juice is added to it, the container becomes 2/3 full. What is the capacity of the container?

Answer: B. 4 litres

Let the capacity be X.
The difference in the fractions is 2/3 - 1/6.
Convert to a common denominator: 4/6 - 1/6 = 3/6 (which simplifies to 1/2).
So, 1/2 of the container equals 2 litres.
Total capacity = 2 * 2 = 4.
Final Answer: 4 litres.
