Correct Answer: 8%
Solution :
Given: List price = Rs. 1,500
Net price = Rs. 1,242
1st discount = $\frac{10}{100} × 1500$
= 150
Price after 1st discount = 1500 – 150 = 1,350
Difference between price after 1st discount and net price = 1350 – 1242 = 108
2nd discount = $\frac{\text{Difference}}{\text{Price after 1st discount}}×100$
= $\frac{108}{1350}×100$
= 8%
Hence, the correct answer is 8%.
