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
Explanation:
please thanks.
Let the price of 1 chair be Rs x and the price of 1 table be Rs y.
The price of 3 chairs and 2 tables is 4500 rupees
3x + 2y = 4500. .. (1)
Price of 5 chairs and 3 tables is 7000 rupees
5x + 3y = 7000. ..(2)
Multiply (1) with 3 and (II) with 2
9x + 6y = 13500. .. (3)
10x + 6y = 14000. ..(4)
subtracting (4) from (3)
9x+6y= 13500
- ___________
10x+6y=14000
_____________
x = 500
Putting this value of x in I
3 x 500 + 2y = 4500
1500 + 2y = 4500
→ 2y = 4500 - 1500 = 3000
y = 1500
Price of 2 chairs and 2 tables will be
= 2x + 2y
= 2(x+y)
= 2 (500 + 1500)
= 2 x 2000
= 4000
Thus, the price of 2 chairs and 2 tableswill be Rs 4000.
