Question

2 chairs and 3 tables cost ₹5650 where 3 chairs and 2 table cost ₹7100 find the cost of a chair and a table separately

Answer 1

Answer:

cost of a chair is Rs.2000 and cost of a table is Rs.550

Answer 2

Explanation:

let the cost of chairs be "x" and the cost of tables be "y".

In first case,2x+3y=5650-----------equation(1)

In second case,3x+2y=7100-------equation(2)

Multiplying Equation(1) by 2,we get:

→4x+6y=11300---------Equation(3)

Multiplying Equation (2) by 3,we get:

→9x+6y=21300--------Equation(4)

Now Equation (4) - Equation(3),we get:

→ 9x+6y=21300

- 4x+6y=11300

(-) (-) (-)

–––––––––––

5x =10000

→ x= 2000-----COST of CHAIRS

Putting the value of "x" in Equation(2),we get:

→3×2000+2y=7100

→6000+2y=7100

→2y=7100 - 6000

→2y=1100

→y=550------COST of TABLES
