Notes
Discount:
- Discount is a reduction given on the Marked Price (MP) of the article.
- This is generally given to attract customers to buy goods or to promote sales of the goods. You can find the discount by subtracting its sale price from its marked price.
So, Discount = Marked price - Sale price.
I. Discount can be calculated when a discount number is given.
Discount = Marked price - Sale price
1) An item marked at Rs. 840 is sold for Rs. 714. What is the discount?
Solution:
Discount = Marked Price - Sale Price
= Rs. 840 – Rs. 714
= Rs. 126.
II. Discount can be calculated when the discount percentage is given.
Discount = Discount % of Marked Price
1) A toy train priced Rs. 800 is available at a discount of 4%. Find a discount.
Solution:
Discount = Discount % of Marked price
Discount = 4% of 800 = `4/100 × 800`
Discount = Rs. 32
Example
An item marked at Rs. 840 is sold for Rs. 714. What is the discount and discount %?
Discount = Marked Price – Sale Price
= Rs. 840 - Rs. 714
= Rs. 126
On the market price of Rs. 840, the discount is Rs. 126.
Discount = `126/840 xx 100% = 15%`.
