The price of 2 tables is equal to the price of 5 chairs. If the price of a chair is Rs. 500 then, what is the average price of 6 tables and 9 chairs?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. Rs 800.
Given that,
The price of 2 tables = The price of 5 chairs
If the price of a chair is Rs. 500
Then, the price of 5 chairs = 5 × 500 = Rs 2500
So, the price of 2 tables = 2500
The price of a table = 2500/2 = Rs 1250
Hence,
The average price of 6 tables and 9 chairs = (6 × 1250 + 9 × 500)/(6 + 9)
⇒ (7500 + 4500)/15 = 12000/15 = Rs 800
