Answer 2

Answer:

The answer is Rs. 300

Step-by-step explanation:

Let the cost of 1 chair be x

Let the cost of 1 table be y

Case I : 6x+2y=500.......(1)

Case 2 : 3x+3y=450........(2)

Multiply 2 in (2) both sides

3x×2+3y×2=450×2

6x+6y=900.......(3)

Subtract (1) from (3)

6x+6y=900

6x+2y=500

(-) (-) (-)

4y=400

y=100

Putting the value of y in (1)

6x+200=500

6x=300

x=50

The cost of 2 chair and 2 tables = Rs. 2×100+2×50

The cost of 2 chair and 2 tables = Rs. 300
