Assume that

cost of table = x

cost of chair = y

Now, cost of 2 tables and 3 chairs is ₹3500

i.e. 2x + 3y = 3500 ------------------ (1)

Now, cost of 3 tables and 2 chairs is ₹4000

i.e. 3x + 2y = 4000 ------------------ (1)

3•(1) - 2•(2), we get

6x + 9y = 10500

6x + 4y = 8000

‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾

5y = 2500

y = 500 (Cost of a chair is ₹500)

From equation (1):

2x + 3y = 3500

Substituting y = 500,

2x + 3(500) = 3500

2x + 1500 = 3500

2x = 2000

x = 1000 (Cost of a table is ₹1000)

Hope it helps!

Answer:

Cost of a table=1000

Cost of a chair=500

Step-by-step explanation:

Let

table=x

Chair=y

Given,

2 tables=2x

3 chairs=3y

=>2x+3y=3500/- ------------------------(1)

3 tables=3x

2 chairs=2y

=>3x+2y=4000/- ------------------------(2)

Multiply (1) with 2

=>2(2x+3y)=2(3500)

4x+6y=7000 -----------------------(3)

Multiply (2) with 3

=>3(3x+2y)=3(4000)

9x+ 6y=12000----------------------(4)

(4)-(3)

=>9x+6y=12000

(-) 4x+6y=7000

(-) (-) (-)

-------------------------------

5x=5000

-------------------------------

x=1000

Substituting x in 1,

2(1000)+3y=3500

3y=3500-2000

3y=1500

y=500

Hope this helps you
