1. A glass when full of milk, weighs one kg. When half full it weighs 3/4 kg; what is the weight of the empty glass?
- A. .45 kg
- B. .45 kg
- C. .45 kg
- D. .45 kg
Answer: Option D
Explanation:
Weight of 1/2 glass of milk = 1 - 3/4 = 1/4 kg
So, weight of full glass of milk = 2 × 1/4 = 1/2 kg
So, weight of the glass = 1 - 1/2 = 1/2 kg = 0.5 kg
