If Ahmed purchases a Watch for Rs 600 and pays 15% sales tax, the total amount spent on purchase is?
Correct answer: D. 690
- A. 660
- B. 670
- C. 680
- D. 690
- E. 700
Explanation
The sales tax is 15% of 600 Rs: 0.15 x 600 Rs = 90 Rs. Adding the tax gives 600 Rs + 90 Rs = 690 Rs. The likely mistake is choosing 660 Rs by adding only 10% instead of 15%.
