Question

Anil bought a 10 kg water-melon in Bangalore that had $99\%$ water. After the water-melon was left outdoors for a day, it was $95\%$ water. What was the weight of the dehydrated water-melon?

• A. 9.6 kg
• B. 9.5 kg
• C. 2 kg
• D. None of these

Answer 1

The correct option is C

2 kg

Initially, there was 0.1 kg of dry part + 9.9 kg of water. After dehydration, 0.1 kg of dry part is $5\%$ of total water-melon's weight. Hence, weight of dehydrated water-melon is 2 kg.
