Question 110 (i)
A store is having a 25% discount sale. Sheela has a Rs.50 gift voucher and wants to use it to buy a board game marked for Rs.320. She is not sure how to calculate the concession she will get. The sales clerk has suggested two ways to calculate the amount payable. Method 1 Subtract Rs.50 from the price and take 25% off the resulting price. Method 2 Take 25% off the original price and then subtract Rs.50.
Do you think both the methods will give the same result? If not, predict which method will be beneficial for her.

Marked price of board game = Rs. 320
Discount in store = 25 %
Sheeta have a gift voucher value = Rs. 50
In method 1 Rs. 320 - Rs. 50 = Rs. 270
Now, 25 % discount on Rs. 270 = 270 - 25100×270
= 270 - 67.5 = Rs. 202.5
In method 2 25 % off on Rs. 320, then subtract Rs. 50
=320−25100×320−50=320−80−50=Rs.190
Hence, method 2 will be beneficial for her.
