Question

A beaker filled with water has a weight of 16 kg when it is full and a weight of 13 kg when it is one-fourth full. Find the weight of the empty beaker.

• A. 10 kg
• B. 13 kg
• C. 14 kg
• D. 12 kg

Answer 1

The correct option is D

12 kg

Let the weight of the empty beaker be x.

Let the weight of the water which can occupy the full container be y.

x + y = 16

$\frac{3}{4}y=3$

$⟹y=4$

$\therefore x=12kg$
