The printed price of a TV set is ₹10,000. After two consecutive discounts, it is sold for ₹8,100. What is the second discount if the first one is 10%?

Show answer & explanation

Correct answer: B

Explanation

Marked Price = 10,000
First Discount = 10%
Final Selling Price = 8,100
According to the formula:
Price after discount = Original Price × (1 − Discount/100)
Price after the first discount =10,000×(1−10100)=9,000= 10,000 \times \left(1 - \frac{10}{100}\right) = 9,000
After the second discount:
8,100=9,000×(1−d100)8,1009,000=1−d1000.9=1−d100d100=0.1d=10%8,100 = 9,000 \times \left(1 - \frac{d}{100}\right) \\ \frac{8,100}{9,000} = 1 - \frac{d}{100} \\ 0.9 = 1 - \frac{d}{100} \\ \frac{d}{100} = 0.1 \\ d = 10\%
