Two miscible liquids of densities `1.2gm//cm` and `1.4gm//cm` aer mixed with a proportion ratio of their volumes equal to 2.5: what is the density of redulting liquid?

Explanation

To find the density of the resulting liquid when two miscible liquids are mixed, we can use the formula for the density of a mixture. Here’s a step-by-step solution:

### Step 1: Identify the given values
- Density of liquid 1, \( \rho_1 = 1.2 \, \text{g/cm}^3 \)
- Density of liquid 2, \( \rho_2 = 1.4 \, \text{g/cm}^3 \)
- Volume ratio of liquid 1 to liquid 2, \( V_1 : V_2 = 2.5 : 1 \)

### Step 2: Express volumes in terms of a common variable
