If the cost price of 30 tables is equal to the selling price of 40 tables, then what is the loss percentage ?

Given:

If the cost price of 30 tables is equal to the selling price of 40 tables, then what is the loss percentage?

Formula used:

Loss % = \(\frac{\text(Cost Price - Selling Price)}{Cost Price}\) × 100

Calculation:

Let CP of 1 table = ₹C

Let SP of 1 table = ₹S

Given: 30C = 40S

⇒ S = \(\frac{\text30C}{40}\)

⇒ S = \(\frac{\text3C}{4}\)

Loss = CP - SP

⇒ Loss = C - \(\frac{\text3C}{4}\)

⇒ Loss = \(\frac{C}{4}\)

Loss % =\(\frac{C}{4}/{C}\) × 100

⇒ Loss % = \(\frac{1}{4}\) × 100

⇒ Loss % = 25%

∴ The correct answer is option 1.
