## Question

### Solution

Correct option is

2.79 g/cc

As the beaker floats in water when less than half filled with water, it will float just fully submerged when half filled. In this situation, mass of beaker + mass of water in it

i.e., outer volume of beaker

Now as inner volume of beaker is given to be 500 cc, so the volume of the material of beaker = 640 – 500 = 140 cc. But as mass of beaker is 390 g, so density of material of beaker

= 2.79 g/cc
