Question 2:
If marked price = ₹990 and percentage of discount is 10, then find the selling price.
ANSWER:
10% discount is given on the marked price. Therefore, if marked price is ₹ 100, then selling price is ₹ 90.
Let the selling price be ₹ x when the marked price is ₹ 990.
∴x990=90100∴x990=90100
⇒x=90100×990⇒x=90100×990 = ₹ 891
Thus, the selling price is ₹ 891.

Question 3:
If selling price = ₹900. Discount is 20%, then find the marked price.
ANSWER:
20% discount is given on the marked price. Therefore, if marked price is ₹ 100, then selling price is ₹ 80.
Let the marked price be ₹ x when the selling price is ₹ 900.
∴900x=80100∴900x=80100
⇒x=10080×900⇒x=10080×900 = ₹ 1,125
Thus, the marked price is ₹ 1,125.

Question 4:
The marked price of the fan is 3000 rupees. Shopkeeper gave 12% discount on it. Find the total discount and selling price of the fan.
ANSWER:
12% discount is given on the marked price. Therefore, if marked price is ₹ 100, then selling price is ₹ 88.
Let the selling price be ₹ x when the marked price is ₹ 3,000.
∴x3000=88100∴x3000=88100
⇒x=88100×3000⇒x=88100×3000 = ₹ 2,640
So, the selling price of the fan is ₹ 2,640.
∴ Discount = Marked price − Selling price = ₹ 3,000 − ₹ 2,640 = ₹ 360
Thus, the discount on fan is ₹ 360.

Question 5:
The marked price of a mixer is 2300 rupees. A customer purchased it for Rs. 1955. Find percentage of discount offered to the customer.
ANSWER:
Marked price of the mixer = ₹ 2,300
Selling price of the mixer = ₹ 1,955
∴ Discount = Marked price − Selling price = ₹ 2,300 − ₹ 1,955 = ₹ 345
On marked price of ₹ 2,300, the discount is ₹ 345.
Let the discount be ₹ x.
Now, if the marked price is ₹ 100, then the discount is ₹ x.
∴ x100=3452300x100=3452300
⇒ x=3452300×100x=3452300×100 = 15
Thus, the percentage of discount offered to the customer is 15%.

Question 6:
A shopkeeper gives 11% discount on a television set, hence the cost price of it is Rs. 22,250. Then find the marked price of the television set.
ANSWER:
Let the marked price of the television set be Rs x.
Discount percent on the television set = 11%
If the marked price of the television set was Rs 100, then the customer would have paid (Rs 100 − Rs 11) Rs 89 for the television set.
It is given that cost price of the television set to the customer is Rs 22,250.
∴ 89100=22250x89100=22250x
⇒ x=22250×10089x=22250×10089 = Rs 25,000
Thus, the marked price of the television set is Rs 25,000.
