1. A full can of petrol weights 1.5 kgs. When half full it wights 1 kg. What is the weight of the empty Can?
- A. 0.2 kg
- B. 0.2 kg
- C. 0.2 kg
- D. 0.2 kg
Answer: Option B
Explanation:
Let, the weight of the empty can = X
So, ½ of the can = x +1 kg
1 part of the can = 2(x+1) kg
So, 2(x+1)= 1.5
or, 2x+1 =1.5
or x =.25
