Question

 If 3 chairs and a table cost Rs. 900/= and 5 chairs and 3 tables cost Rs. 2100/=, then the cost of 5 chairs and a table will be * 2 points Rs.1000/= Rs.1100/= Rs. 1200/= Rs.1300/=​

Answer 1

Answer:

1200 rs

Step-by-step explanation:

Let assume price of table = x

and price of chair = y

ATQ

3y + x = 900

or x = 900 - 3y—- eq (1)

5y + 3x = 2100

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

5y + 2700 -9y = 2100

4y = 2100 - 2700

4y = 600

y = 600/4 = 150 rs

so price of 1 chair is 150 rs

and price of 1 table is = 900 - 3(150) = 450 rs

so cost of 5 chair and 1 table will be

5 x 150 + 450

750 + 450

= 1200 rs
