Formulate the fol

Answer :

Let chairs be x and tables be y.


Then the equations are


3x + 2y = 700 i.e. 3x + 2y – 700 = 0


5x + 3y = 1100 i.e. 5x + 3y – 1100 = 0


For cross multiplication method, we write the coefficients as



Hence, we get = =


= =


= =


x = = 100 (Cost of one chair)


y = = 200 (Cost of one table)


Now, total cost of two chairs and three tables,


2x + 3y = 2 (100) + 3 (200) = 200 + 600 = Rs. 800
