While purchasing one item costing Rs. 600 , I had to pay the sales tax at 6% and on another costing Rs. 16000, the sales tax was 10%. What percent of the sales tax I had pay, taking the two items together on an average?

8.8%

9.9%

8.9%

9.8%

✅ Correct Option: 2

Total tax $=0.06\times600+0.10\times16000=36+1600=1636$ . Total cost $=600+16000=16600$ . Average tax $\%=\frac{1636}{16600}\times100\approx9.86\%$ , closest to 9.9%.
