A washing machine has a marked price of ₹30,000. It is sold after two successive discounts. If the first discount is 18% and the final selling price is ₹21,528, what is the percentage of the second discount?

Question

Accepted Answer

1. After first discount: $30000	imes(1-0.18)=30000	imes0.82=24600$.
2. Let second discount be $x\%$. Then $24600	imes(1-x/100)=21528$.
3. So $x/100=1-\dfrac{21528}{24600}=\dfrac{3072}{24600}=\dfrac{128}{1025}$, hence $x=100	imes\dfrac{128}{1025}\approx12.5\%$.
4. Answer: **(c) 12.5%**.
