Question

A big mega store is having a festival sale and all the items are having 25% discount.
Vivek is having a Rs 50 Gift card and he has chosen a game whose marked price is Rs 300. Now Vivek is confused how to calculate the discount and what remaining money need to be paid to the clerk
The sales clerk has suggested two ways to calculate the concession
Method 1. Subtract Rs 50 from Marked price and then take 25% discount on the remaining amount
Method 2. Take 25% discount on the Marked price and then Subtract Rs 50 from it Now the question for you
a) Do you think both the method will give same result? if not predict which method will be beneficial to him
b) Calculate the amount Vivek has to pay to the clerk in each case
c) What method do the store actually uses? And why?​

Answer 1

Answer:

a) no. Method 2 is beneficial to vivek

b) method 1

  300 - 50 = 250

  250 - 25% of 250 = 250 - 62.5 = 187.5

 method 2

  300 - 25% 0f 300 = 300 - 75 = 225

  225 - 50 = 175

c)The store uses the second method

  Because the price has 25% discount even if vivek have or have not a gift card. So the amount from the gift card should be subtracted after discount.

Answer 2

Given:

According to question we have

Lets first calculate using both the method

Method 1 :-

MP = Rs.300

MP After Rs.50 deduction = Rs.300 -50

=Rs.250

Discount = 25% of Rs.250

= Rs.62.5

Price after discount= Rs.250 - Rs.62.5

= Rs.187.5

Method 2 :-

MP = Rs.300

Discount = 25% of Rs.300

= Rs.75

Price after discount= Rs.300 - Rs.75

= Rs.225

Amount left after Rs.50 gift deduction = Rs.225 - 50 = Rs.175

So both the method gave different result.

And method -2 is beneficial.

Method -2 is correct method and this is used by the stores
