Question

A bottle filled with a liquid weighs 1 kg. The liquid alone weighs 3 kg more than the empty bottle. If the bottle is completely filled, how much will the contents weigh?

a) 4 kg
b) 3 kg
c) 1 kg
d) 7 kg

Answer 1

The contents of the completely-filled bottle will weigh 4 kg.

Step-by-step explanation:

To find the weight of the contents in the completely-filled bottle, we need to subtract the weight of the empty bottle from the total weight of the bottle filled with liquid. The liquid alone weighs 3 kg more than the empty bottle, so the weight of the liquid is 1 kg + 3 kg = 4 kg. Therefore, the contents of the completely-filled bottle will weigh 4 kg.
