the cost of 10chairs and 15tables is 15525.what is the cost of 8chairs and 12tables?​

Answer 1

Let the cost of one chair = x rupees  

Let the cost of one table = y rupees

10x+15y = 15525

5(2x+3y) = 5(3105)

2x+3y = 3105  eq 1

Cost of 8 chairs and 12 tables = 8x+12y

= 4(2x+3y) rupees            (Substituting the value from eq 1)

= 4(3105) rupees

= 12420 rupees
