Question : Six tables and twelve chairs were bought for Rs. 7,800. If the average price of a table is Rs. 750, then the average price of a chair would be:
Option 1: Rs. 250
Option 2: Rs. 275
Option 3: Rs. 150
Option 4: Rs. 175
Correct Answer: Rs. 275
Solution :
Average price of a table = Rs. 750
Price of six tables = 750 × 6 = Rs. 4500
Money spent on chair = Total money spent – Money spent on table
Money spent on chair = 7800 – 4500 = Rs. 3300
Thus, 12 chairs cost Rs. 3300
Average price of a chair is $\frac{3300}{12}$ = Rs. 275
Hence, the correct answer is Rs. 275.
