A shopkeeper allows a discount of 10\% on the marked price of an item but charges a sales tax of 8\% on the discounted price. If the customer pays ₹ 680.40 as the price including the sales tax, then what is the marked price of the item?
(a)₹ 630
(b)₹ 700
(c)₹ 780
(d)None of these
Answer
Answer (as printed): B
Explanation
Let the marked price be ₹ $x$. Then, $108 \%$ of $90 \%$ of $x=680.40$ $$\Rightarrow \quad \frac{108}{100} \times \frac{90}{100} x=680.40 \Rightarrow x=\left(\frac{68040 \times 100}{108 \times 90}\right)=₹ 700 .$$
