Question

A dealer mark his good 20% above cost price and allows a discount of 10% to his customer .his gain % is ?​

Answer 1

Answer: Gain % = 8%

Step-by-step explanation:

Let the price be 100.

= 20% of 100

= $\large{\frac{20}{100}}$ × 100

= 20

So, Cost price = 100 + 20 = ₹120

When 10% discount is allowed

10% of 120

= $\large{\frac{10}{100}}$ × 120

= 12

So Selling price = 120 - 12 = ₹108

SP > CP, so its profit

P = SP - CP

P = 108 - 100

P = ₹8

Profit % = $\large{\frac{8}{100}}$ × 100

Profit % = $\large{\boxed{8\:percent}}$
