Three liquids of densities `d, 2d` , and `3d` are mixed in equal volumes. Then the density of the mixture is

A

6 D

B

`1.4 D`

C

2 D

D

3 D

Text Solution

Verified by Experts

The correct Answer is:
C
If equal volume of liquids of density `rho_(1),rho_(2)rho_(n)` are mixed the density of the mixture is equal to the arithmetic mean of liquid densities `rho_(1),rho_(2)rho_(n)`.
i.e., `rho_(mix)= rho_(1)+ rho_(2)+ --- + rho_(n)`
