The density of a certain oil on frying becomes 0.4 kgm3 with the volume of 20m3. what will be its initial volume when its initial density is 0.8 kgm3 assuming no loss of oil due to spillage?

A.

12m3

B.

10m3

C.

8m3

D.

5m3

Correct answer is B

Density (D) = massvolume

= 0.4 \times 20 = 8kg

The initial volume = \frac{Mass}{\text{Initial density}}

= \frac{8}{0.8} = 10m^{3}
