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
[ ] - [ ] = 90 rupees
Hence, when the discount is [ ] then the selling price is [ ] rupees.
Suppose when the discount is [ ] rupees, the selling price is x rupees.

∴ the customer will get the item for 153 rupees.
Answer :
Suppose, marked price of the item = 100 rupees
Therefore, for customer that item costs
[100] - [10] = 90 rupees
(Given the discount is 10% on the marked price.
Discount = 0.10
100 = 10 rupees
Also, we have Cost Price = Marked Price - Discount
Cost Price = 100 – 10 = 90 rupees)
Hence, when the discount is [10] rupees then the selling price is [90] rupees.
Suppose when the discount is [17] rupees, the selling price is x rupees (as it is given that customer gets a 17 Rupees discount).
=
=
= [153]
∴ the customer will get the item for 153 rupees.
