Let the Price of a Chair be Rs x Let the price of a Table be Rs y

The price of 33 chairs and 22 tables is 4500 RS

⇒3x+2y=4500 ____ (1)

price of 55 chairs and 33 tables is 7000Rs, ⇒5x+3y=7000 ______(2)

price of 55 chairs and 33 tables is 7000Rs, ⇒5x+3y=7000 ______(2) Solving Equation 1 and 2 ,we get-

price of 55 chairs and 33 tables is 7000Rs, ⇒5x+3y=7000 ______(2) Solving Equation 1 and 2 ,we get- ∴ x=500 & y=1500

⇒ Price of 2 Chairs and 2 Tables =2x+2y

⇒ Price of 2 Chairs and 2 Tables =2x+2y =2(x+y)

⇒ Price of 2 Chairs and 2 Tables =2x+2y =2(x+y) =2(500+1500)

⇒ Price of 2 Chairs and 2 Tables =2x+2y =2(x+y) =2(500+1500) =2×2000

⇒ Price of 2 Chairs and 2 Tables =2x+2y =2(x+y) =2(500+1500) =2×2000 = Rs. 4000

⇒ Price of 2 Chairs and 2 Tables =2x+2y =2(x+y) =2(500+1500) =2×2000 = Rs. 4000Therefore ,Cost of 2 Chairs and 2 Tables is 4000 RS.
