Question

let's calculate and. write the discount aquivalent to successive discounts of 20%,10% and 5%​

Answer 1

Answer:

Let the marked price =Rs100

After a discount of 20%, the price = 100−20% of100 = 100−

100

20

×100 = 100−20=80

After a further discount of 5%, price = 80−5% of80 = 80−

100

5

×80 = 80−4 = Rs76

Final Selling = Rs76

Total Discount = 100−76=Rs24

Thus, discount % =

100

24

×100 = 24%

Answer 2

Answer:

Answer:

The single discount is 31.6%.

Solution:

Let us consider that the marked price of a product is 100.

Applying 20% discount on it, we get,

(20 / 100) * 100 = 20

New price = 100 - 20 = 80

Applying 10% discount on it, we get,

(10 / 100) * 80 = 8

Now the new price is = 80 - 8 = 72

Applying 5% discount on it, we get,

(5 / 100) * 72 = 3.6

Now the new price = 72 - 3.6 = 68.4

Applying a single discount of 31.6% on 100, we get,

(31.6 / 100) * 100 = 31.6

New price = 100 - 31.6 = 68.4

Hence the single discount is 31.6%.
