Three chairs and two tables cost Rs. 1850. Five chairs and three tables cost Rs. 2850. Then the total cost of one chair and one table is
Given 2 tables and 3 chairs=Rs.1850
Let cost of 1 chair =Rs.x
Cost of 1 table =Rs.y
Now, we have
3x+2y=1850×5 ...(i)
5x+3y=2850×3 ...(ii)
⇒15x+10y=9250 ...(1)
15x+9y=8550 .... (2)
Subtract (1)-(2), we get y=700.
Substitute values of y in (1), we get
3x+1400=1850
⇒3x=450
⇒x=Rs.150
∴ total cost of 1 chair and 1 table is 150+700=Rs.850.
