Explanation:

- Radha purchased the fridge and washing machine for a total of Rs 57300.

- The selling price of the fridge included a profit of 15%.

- The washing machine was sold at a 24% loss.

- They were both sold at the same price, so the selling price of the fridge equals the selling price of the washing machine.

- Let the cost price of the fridge be Rs F and the cost price of the washing machine be Rs W.

From the problem:

- F + W = 57300

- Selling price of the fridge = F * 1.15

- Selling price of the washing machine = W * 0.76

- F * 1.15 = W * 0.76

- Solving these equations will give the values of F and W.

- After solving, we find that W = Rs 34500 is the correct option.

Option 2 is the correct choice.
