Question

3. A shopkeeper allows a discount of 10% on the marked price of an article. What price should be marked on the article that costs him 600 so that he makes a profit of 20%?​

Answer 1

Answer:

Cost of camera=600

Shopkeeper get 20% profit=\frac{600 \times 120}{100}=720

100

600×120

=720

Now he allowed 10% discount

So marked price is \frac{90x}{100}=720

100

90x

=720

\frac{90x}{100}=720

100

90x

=720

x=\frac{720 \times 100}{90}x=

90

720×100

x=800x=800

Hence the marked price should be Rs.800
