The weight of a liquid varies directly with its volume. A liquid that weighs 12 kg has a volume of 3 liters. What will be the weight of a liquid that has a volume of 4 liters?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e.16 kg.
Weight of Liquid ∝ Volume of the liquid
Weight of Liquid = k(Volume of the liquid)
When weight = 12 kg and volume = 3 liters
⇒ 12 = 3k
⇒ k = 4
When volume = 4 liters
Weight = 4k = 4(4) = 16 kg
