3 chairs and 2 tables cost Rs. 700 and 5 chairs and 3 tables cost Rs. 1100. What is the cost of 1 chair and 2 tables?
Let the chair =x and table =y 3x +2y=800 … (1) ×5 5x+3y =1300 … (2) ×3 15x+10y =4000 … (3) 15x +9y =3900 … (4) Equation (4)-(3). Y =100. X =200. So now- The cost price of 1 chair and 2 tables- =200+2×100=400Rs.
