Answer 1

Answer:

Answer

Let the price of 1 chair be Rs x

Let the price of 1 table be Rs y

Then -

3x+2y=4500 ____ (1)×3

5x+3y=7000 ______(2)×2

9x+6y=13500

10x+6y=14000

x=−500

x=500

3(500)+2y=4500

2y=4500−1500

2y=3000

y=1500

∴ Price of 2 chairs and 2 tables =2x+2y

=2(x+y)

=2(500+1500)

=2×2000

= Rs. 4000

Total Money= 4000

price of 2 chairs= 1000

price of two table =3000

Answer 2

Answer:

The price of 2 chairs and 2 tables are Rs.1000 and Rs.3000

Step-by-step explanation:

Let the price of 1 chair be x

Let the price of 1 table be y

Price of 3 chairs = 3x  

Price of 2 table = 2y

The price of 3 chairs and 2 tables is 4500

So,3x+2y=4500 -- A

Price of 5 chairs = 5x

Price of 3 tables = 3y  

The price of 5 chairs and 3 tables is 7000

So,5x+3y=7000 --B  

Solve A and B

(x,y)=(500,1500)  

The price of 1 chair = 500

Price of 2 chairs = 2(500)=1000

Price of 2 tables = 2(1500)=3000

Hence The price of 2 chairs and 2 tables are Rs.1000 and Rs.3000
