Question

The cost of a pair of roller skates at a shop was Rs. 450. The sales tax charged was 5%. Find the bill amount.

Answer 1

Hint:- Here we go through by finding the value of 5% of the roller skates price then adding it to the original scooter price because the price is increased by adding the sale tax.

Complete step-by-step answer:
Given that price of the roller skates is Rs.450
And now it is given that the sale tax is applied at the rate of 5%.
So first we have to find the value of 5% of 450. By this step we know that by what amount the price will increase.
5% of 450=$\dfrac{5}{{100}} \times 450 = 22.5$ (as we know x% is written as $\dfrac{x}{{100}}$and we also know “of” is symbol of multiply that we study in BODMAS).
Now, price of roller skates after applying the tax of 5%= 450+22.5=Rs.472.5
Hence, the required answer is Rs.472.5

Note:- Whenever we face such a question the key concept for solving the question is first find out the value of given percentage by applying the method of finding the value of finding the percentage then if it is increasing then add the value to the original price if its decreasing the subtract from the original price.
