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

Correct option is B

Given:

Cost of roller skates = ₹450

Sales Tax = 5%

Formula Used:

Bill Amount = $$\text{Cost Price} + \left( \frac{\text{Tax \%} \times \text{Cost Price}}{100} \right)$$​​

Solution:

Tax = $$\frac{5}{100} \times 450 = 22.5$$​​

Bill Amount = 450 + 22.5 = ₹472.50
