Answer: The relative density of mixture is \frac{18d}{11}

Explanation:

The equation used to calculate density of a substance is given by:

\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}

We are given:

Density of liquid 1 = d

Density of liquid 2 = 2d

Density of liquid 3 = 3d

To calculate the relative density of a mixture, we use the equation:

\rho_{mix}=\frac{m_1+m_2+m_3}{V_1+V_2+V_3}

where,

m_1\text{ and }V_1 are the mass and volume of liquid 1

m_2\text{ and }V_2 are the mass and volume of liquid 2

m_3\text{ and }V_3 are the mass and volume of liquid 3

We are given:

Mass of all the three liquid are equal to 'm' because they are mixed in equal proportions of weight.

m_1=m\\V_1=\frac{m}{d}\\\\m_2=m\\V_2=\frac{m}{2d}\\\\m_3=m\\V_3=\frac{m}{3d}

Putting values in above equation, we get:

\rho_{mix}=\frac{m+m+m}{\frac{m}{d}+\frac{m}{2d}+\frac{m}{3d}}\\\\\rho_{mix}=\frac{3\times 6d}{11}=\frac{18d}{11}

Hence, the relative density of mixture is \frac{18d}{11}
