A trader allows a discount of 15% on the marked price of the goods in his shop. However, he still makes a gross profit of 36% on the cost price. Find the profit percent, he would have made, had he sold the goods at the marked price.
उत्तर
Let the C.P. be Rs.100
Given that the profit%
= 36% on the C.P.
Profit%
= `"profit"/"C.P." xx 100`
⇒ 36% = `"profit"/(100) xx 100`
⇒ profit = Rs.36
S.P. = C.P. + Profit
= 100 + 36
= Rs.136
Let the marked price of the goods be Rs. x.
Discount = 15% of M.P.
= `(15)/(100) xx x`
= Rs.`(15x)/(100)`
So, S.P. = M.P. - Discount
⇒ 136 = Rs.`(x - (15x)/100)`
⇒ x = Rs.`(136 xx 100)/(85)`
⇒ x = Rs.160%
If the goods were sold at the M.P., that S.P. = M.P.
So, M.P. - C.P.
= 160 - 100
= 60
= profit
Profit%
= `(60)/(100) xx 100`
= 60%
Hence, the profit percent would be 60%.

After offering discount of 10% on marked price, a customer gets total discount of 17 rupees. To find the cost price for the customer, fill in the following boxes with appropriate numbers and complete the activity.
Suppose, marked price of the item = 100 rupees
Therefore, for customer that item costs `square` - `square` = 90 rupees
Hence, when the discount is `square` then the selling price is `square` rupees.
Suppose when the discount is `square` rupees, the selling price is x rupees.
∴ `x/square=square/square`
∴ x = `(squarexxsquare)/square`
∴ x = `square`
∴ the customer will get the item for 153 rupees.
