Question

If the cost of 5 table exceeds the cost of 8 chair by rs 150 then by taking cost of a chair as rs x and that of a table as rs y , from a linear equations and draw it's graph

Answer 1

Let cost of 1 table be x rupees

And cost of 1 chair be y rupees

therefore , cost of 5 tables =5x

cost of 8 chairs= 8y

and 5x-8y=156

this is the linear equation in two variables x and y that represents the statement.

Also given that one chair is 240 rs. Therfore cost of 1 table would be x= (156+8(240))/5=415.2
