Question

The marked price of a chair is ₹1,800 and a discount of 18% is offered on the marked price. What additional discount must be offered to the customer now to bring the net price to ₹1,220? (Correct to two places of decimals.)

• A. 13.47%
• B. 31.47%
• C. 17.34%
• D. 14.37%

Answer 1

Answer:

C. 17.34%

Marked price = ₹1800

First discount = 18%

Discount amount:

$1800\times\frac{18}{100}=324$

Price after first discount:

1800 − 324 = ₹1476

Let the additional discount be (x%).

Then:

$1476\left(1-\frac{x}{100}\right)=1220$

$1-\frac{x}{100}=\frac{1220}{1476}$

$\frac{x}{100}=1-\frac{1220}{1476}=\frac{256}{1476}$

$x=\frac{256}{1476}\times100 \approx 17.34$

Additional discount = 17.34%
