Question

the price of 3 chairs and 2 tabels is 4500 rupees and price of 5 chairs and 3 tables is 7000 rupees then find tha total price 2 chairs and 2 tables answer this question​

Answer 1

Answer:

4000 rupees

Step-by-step explanation:

let price of one chair be = c

and price of one table = t

3c + 2t = 4500      (By condition)

5c + 3t = 7000

9c + 6t = 13500   --- 1

10c + 6t = 14000   --------2

subtract 2 from 1

c = 500 rupees

substitute c = 500 in any eqn.

since 3c + 2t = 4500

3(500) + 2t = 4500

2t = 4500 - 1500

t = 3000/2

t = 1500 rupees

now it is asked price of 2c + 2t

= 2(500) + 2(1500)

= 1000 + 3000

'

= 4000 rupees is the answer
