Question

The selling price of an article is Rs. 900. The
shopkeeper allows successive discounts of 11%
and 21%Then what be the total discount
given on the article?​

Answer 1

Answer:

₹380.

Step-by-step explanation:

SP = ₹900.

Let the successive discounts be x and .

Then,

Discount x = 11%.

Discount y = 21%.

By SP formula,

SP = (1- x/100) (1- y/100) × MP

⇢ 900 = (1- 11/100) (1- 21/100) × MP

⇢ 900 = (89/100) (79/100) × MP

⇢ MP = 100/89 × 100/79 × 900

⇢ MP = 900000/7031

⇢ MP = ₹1280.

Now,

MP = ₹1280.

SP = ₹900.

Discount = MP - SP

⇢ Discount = ₹1280 - 900

⇢ Discount = ₹380.

Therefore, total discount given on the article is ₹378.

Used Abbreviations

MP = Marked Price.

SP = Selling Price.

x = 1st discount (11%).

y = 2nd discount (21%).
