Question

8 chair and 5 table cost 10500. 5 chairs and 3 tables cost 6450. What is the cost of 1 chair

Answer 1

ANSWER:

750,900

Step-by-step explanation:

Let the cost of a chair is x Rs and the cost of a table is y Rs.

Then,

8x+5y=10500→(1)

5x+3y=6450→(2)

Multiplying (1) with 3 and (2) with 5, and then subtracting (2) from (1),

24x+15y−25x−15y=31500−32250

−x=−750⇒x=750

Putting value of x in (1),

8(750)+5y=10500

⇒5y=10500−6000

⇒y=900

∴ Cost of the chair is 750 Rs and cost of the table is 900 Rs.
