Question

During a sale, a shop offered a discount of 10% on the marked prices of all the items. What

would a customer have to pay for a pair of jeans marked at ₹1450 and two shirts marked at
₹850 each?

Answer 1

$2,835

Explanation:

10% in a simple number because all you have to do is move the decimal point one place to the left to get 10% of it. 1,450.00 becomes 145.000 and 850.0 becomes 85.00. However, the proper way to find percentages is to take the percent in decimal form and multiply by the original number (10% is 0.1, 50% is 0.5, 17% is 0.17, and 8% is 0.08). 1450*0.1=145 and 850*0.1=85. THIS IS JUST THE DISCOUNT, it is NOT the final price, this is a common mistake. subtract the discount from the original price, 1450-145=1305 and 850-85=765. There are 2 shirts so the total cost would be 1305+765+765=2835. The very expensive clothes cost $2,835 in total.

Answer 2

₹2835

Explanation:

Working out discount of 10% of jeans at ₹1450:

10% of 1450 = 1450/10 = ₹145

the price would now be ₹1450 - ₹145 = ₹1305

Working out discount of 10% of a shirt at ₹850:

10% of 850 = 850/10 = ₹85

the price would now be ₹850 - ₹85 = ₹765

so the price of two shirts = ₹765 × 2 = ₹1530

the total the customer would have to pay:

₹1305 + ₹1530 = ₹2835
