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:
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
