Ahmed bought 6 chairs and 2 tables for RS. 6300 while Ali bought 2 chairs and one table of the same quality from the same shop for RS. 2600. Find the price of a chair?
Answer: Rs. 550
Explanation
Given:
1. 6x + 2y = 6300
2. 2x + y = 2600
Multiplying equation (2) by 2:
4x + 2y = 5200
Subtracting:
(6x + 2y) - (4x + 2y) = 6300 - 5200
2x = 1100
x = 550
