Let the cost of one chair be x.
Let the cost of one table be y
According to the question,
- 3x+2y=700 ...........(1)
- 5x+3y=1100 ...........(2)
Multiply (1) with 3 and (2) with 2 and subtract
- 9x+6y=2100
- 10x+6y=2200 / −x+0=−100
- x=100 substitute in (1)
- 3(100)+2y=700
- 300+2y=700
- 2y=400
So, the total cost of 2 chairs and 3 tables will be
- =2×100+3×200
- =200+600=Rs. 800
Hence, this is the answer.
