Solution

Let the C.P. be Rs.100.
Given that the profit% = 21% on the C.P.
Profit% = `"profit"/"C.P." xx 100`

= 21% = `"profit"/(100) xx 100`
⇒ profit = Rs.21
S.P. = C.P. + Profit
= 100 + 21
= Rs.121

Let the market price of the goods be rs. x.
Discount = 12% of M.P.
= `(12)/(100) xx x`
= Rs.`(12x)/(100)`
So, S.P. = M.P. - Discount
⇒ 121 = Rs.`(x - (12x)/100)`
⇒ x = Rs.`(121 xx 100)/(88)`
⇒ x = Rs.137.5%
If the goods were sold at the M.P., that S.P. = M.P.
So, M.P. - C.P.
= 137.7 - 100
= 37.5
= profit
Profit% = `(37.5)/(100) xx 100`
= 37.5%
Hence, the profit percent would be 37.5%.

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.
