Rohit buys an item at 25% discount on the marked price.
Question:

Rohit buys an item at 25% discount on the marked price. He sells it for Rs 660, making a profit of 10%. What is the marked price of the item?

Solution:

Given,

SP of the item $=R$. 660

Discount on the item $=25 \%$

Profit on the item $=10 \%$

We know,

$\mathrm{MP}=\left(\frac{100 \times \mathrm{SP}}{100-\text { Discount } \%}\right)$

$=\left(\frac{100 \times 660}{100-25}\right)$

$=$ Rs. 880

Thus, the marked price of the item is Rs. 880 .
