Thank you for pointing out the mistake. We have corrected the sequence now.
Water in the jug = 1/12
Water added in the jug = 5/6
Total water = 1/2 + 5/6 = 11/12
Water overflowed = 1/4
Capacity of jug = 11/12 - 1/4 = 8/12 = 2/3 L

Answer: D

Solution
The weight of 9 balls = 500 + 500 + 800 = 1800 g
Weight of 1 ball = 200 g
Weight of 5 balls = 1000g
PS: The figure may not be clear. We are replacing it with a more clear figure.
