While purchasing one item costing Rs. 400, I had to pay the sales tax at 7% and on another costing Rs. 6400, the sales tax was 9%. What percent of the sales tax I had to pay, taking the two items together on an average ?
2 + 13/17
Incorrect Answer3 + 2/17
Incorrect Answer5 + 13/12
Incorrect AnswerExplanation:
Total sales tax paid = 7% of Rs, 400 + 9% of Rs. 6400
=Rs. (7/100)*400 + (9/100)*6400 = Rs. (28 + 576) = Rs. 604.
Total cost of the items = Rs. (400 + 6400) = Rs. 6800.
Required percentage = (604 /6800*100) % = 8 15/17%.
Hence, option 1 is the correct answer.
