Question

. Which is better offer: two successive discounts of 20% and 10% or a single discount of
30%?​

Answer 1

Answer:

hello mate

your answer is single discount of 30% is better option.

explanation

let the price be 100

so, cost after 20% discount=100-(100×20/100)

=₹80

price after 10% discount also=80-(80×10/100)

=72

so, we will get the product in ₹72

BUT

in single discount of 30%

price=100-(100×30/100)

=₹70

so we get it in ₹70 only.

so it is better.

hope you understand and it helps you..

Answer 2

Answer:

A single discount of 30% is better offer.

Step-by-step explanation:

Let the discount be applied to Rs.1000

Case 1:

Successive discounts of 20% and 10%

After 20% discount: 1000-(0.2*1000)

=Rs. 800

After 10% discount on Rs. 800 : 800-(0.1*800)

=Rs. 720

Case 2:

Single discount of 30%

: 1000-(0.3*1000)

=Rs. 700

SO A SINGLE DISCOUNT OF 30% IS BETTER
