Roller skates cost Rs 450 and sales tax is charged at 5 per cent. What is the bill amount?
ARs 467.50
BRs 477.50
CRs 472.50
DRs 495.00
Answer & Solution
Correct answer: C. Rs 472.50
1. Sales tax is charged on the selling price and added to the bill.
2. Tax = (5/100) x 450 = Rs 22.50.
3. Bill amount = 450 + 22.50 = Rs 472.50.
4. Note that tax is added, not deducted, so the bill exceeds Rs 450.
