Six tables and twelve chairs were bought for Rs 7800. If the average price of a table is Rs 750, what is the average price of a chair?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Rs 275
Take the cost of the tables out of the total bill; what is left was paid for the twelve chairs.
Cost of 6 tables \(=6\times750=4500\)
Cost of 12 chairs \(=7800-4500=3300\)
\(\displaystyle \text{Average price of a chair}=\frac{3300}{12}=275\)
The average price of a chair is Rs 275.
