Answer 1

Answer:

the cost of 5 chairs and table is rs. 3000

Step-by-step explanation:

let chairs be x and tables be y...

Acc. to question:

⇒3x+y= 900                        eq.(i)

y= 900-3x

⇒5x+3y=2100                      eq(ii)

by putting the value of y in eq.(ii), we get

5x+3(900-3x) =2100

5x+2700-9x= 2100

-4x = -600

x= 150

cost of one chair is rs. 150

now, by putting the value of x in eq.(i), we get

3(150)+ y = 900

450 +y = 900

y = 450

cost of one table is rs.450

now, the cost of 5 chairs and table is: 5( x+y) = 5( 150+ 450)= 3000
