Question

Four chairs two tables cost Rs2500 while six chairs and five tables cost Rs 600.find the cost of one chair and one table separately (use Craer rule by forming pair of linear equations)

Answer 1

Answer:

Answer: cost of one chair = 62.5 Rs

cost of one table = 1125 Rs

Explanation: let cost of one chair be c

                     let cost of one table be t

thus, 4c + 2t = 2500  ....(1)

and,  6c + 5t = 6000 .... (2)

multiply equation (1) by 3 and equation (2) by 2

thus we get,

12c + 6t = 7500

12c + 10t = 12000

subract the new two equations

12c + 6t - 12c - 10t = 7500 - 12000

thus, -4t = -4500

thus, t = 4500/4

t = 1125 Rs

so c = 62.5 Rs
