A person paid 17000 Rs for a motor car after a single discount of 15%. If he is given successive discounts of 5% and 10% then how much he would pay?
[A]17000 Rs.
[B]17010 Rs.
[C]17100 Rs.
[D]18900 Rs.

17010 Rs.
Let ‘x’ be the marked price
Single discount = 15%
=> 100 – 15 = 85
85% of x = 17000
\therefore x = \frac{17000}{85}\times 100 = 20000 Rs.
∴ Required SP =
= 20000\times \frac{95}{100}\times \frac{90}{100}
= 180\times 95 = 17100 Rs.
Hence option [C] is correct answer.
