Question

4 chair and 2 table cost rs 2500while 6 chairs and 5 table cost rs 6000 find the cost of one chair and one table separately use Cramer rule forming pair of linear equations

Answer 1

Answer:

cost of one chair is 62.5 rupees and cost of one table is 1125 rupees

Step-by-step explanation:

let the cost of a chair be x and cost of a table be y

so,4x+2y=2500

6x+5y=6000

according to cramers rule,

x =delta by delta x .similarly , y=delta by delta y

delta=|4 2|

|6 5| =20-12=8

delta x=|2500 2|

|6000 5|

=12500-12000=500

deltay=|4 2500|

|6 6000|

=24000-15000=9000

x=500÷8=62.5

y=9000÷8=1125

therefore x=rupees 62.5 and y=rupees 1125
