Question

The price of 3 chairs and 2 tables is 4500 rupees and price of 5 chairs and 3 tables is 7000 rupees, then find the price of 3 chairs and 5 tables. *​

Answer 1

Step-by-step explanation:

let chair = x

table = y

by question,

3x+2y =4500--------(1)

5x+3y=7000----------(2)

eq. (1) multiply by 3 and eq. (2) multiply by 2

9x+6y=27000

10x+6y=14000

subtracting the terms

9x+6y-10x-6y = 27000 - 14000

-x = 13000

x = - 13000

puri the values of x in (1) eq.

3x+2y = 4500

3(- 13000) + 2y = 4500

- 39000 + 2y = 4500

2y = 4500 + 39000

2y = 43500

y = 43500/2

y = 21750

3 chairs = 3 x = 3(-13000)

= -39000

5 tables = 5y = 5(21750)

= 108750
