Question

. 8 chairs and 5 tables for a classroom cost Rs.10500, while 5 chairs and 3 tables cost

Rs.6450. the cost of each chair will be:

(a) Rs.900 (b) Rs.750 (c) Rs.600 (d) None of these​

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.

Answer 2

Answer:

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
