Question

A pair of pants costs Rs.60 but there is a sale for 40% off the original price. How much will the discount be? How much will I pay for the pants?

Answer 1

Hint: To calculate the discount on the price of the pair of pants, find the value of 40% of Rs.60. Now, to find the amount that will be required to pay for the pants, take the difference of the original price, i.e., Rs.60, and the obtained discount on the price.

Complete step by step answer:
Here, we have been provided with the cost of a pair of pants and it is given that there is a discount of 40% on the original price of the pants. We have been asked to determine the price that will be discounted and the price that we need to pay for the pants.
Now, the original price of the pair of pants = Rs.60
Percentage discount of these pants = 40%
So, the price that is to be discounted on the pair of pants will be equal to 40% of Rs.60. Therefore, we have,
\[\Rightarrow \] Price to be discounted = \[\dfrac{40}{100}\times 60\]
\[\Rightarrow \] Price to be discounted = Rs.24
Hence, the discount on the pair of pants will be Rs.24.
So, we can say that we do not need to pay Rs.24 out of Rs.60. Therefore, the price we need to pay will be the difference between the original price and the price that is discounted. So, we get,
\[\Rightarrow \] Price we need to pay for the pants = Rs. 60 – Rs. 24
\[\Rightarrow \] Price we need to pay for the pants = Rs.36
Hence, we will pay Rs.36 for the pair of pants.

Note:
One may note that we can calculate the price that we need to pay using a different way also. What we can do is we will find the non – discounted percentage on the original price of pants by subtracting 40% from 100%. Now, to calculate the required price to be paid for the pants we will calculate 60% of Rs.60. In this way also we will get Rs.36 as our answer.
