tables
Answers
Let chairs be c,tables be t
3c+2t=4500------(1)
5c+3t=7000------(2)
multiple equation (1) with 3 & (2) with 2
9c+6t=13500
10c+6t=14000
------------------------
c=5000
substitute c value in equation (1)
1500+2t=4500
2t=4500-1500
2t=3000
t=1500
2c+2t=2×5000+2×1500
=10000+3000=13000
Answer:
The total price of 2 chairs and 2 tables is rupees 4000.
Step-by-step explanation:
Let the price of chair be rupees x and that of table be rupees y. Then from the first condition,
3x + 2y = 4500 ... (1)
From the second condition,
5x + 3y = 7000 ... (2)
Multiplying equation (1) by 3 and equation (2) by 2,
9x + 6y = 13500 ... (3)
10x + 6y = 14000 ... (4)
Subtracting equation (3) from equation (4),
(10x + 6y = 14000)
-(9x + 6y = 13500)
——————————
x + 0 = 500
=> 2x = 2 × 500 = 1000 ... (5)
Substituting x = 599 in equation (1)
3(500) + 2y = 4500
=> 1500 + 2y = 4500
=> 2y = 4500 - 1500
=> 2y = 3000 ... (6)
Now, the price of 2 chairs and 2 tables is
Rupees(1000 + 3000) [From (5) and (6)]
= rupees 4000
Hence, the total price of 2 chairs and 2 tables is rupees 4000.
Hope it helps :)
