Answer 1

Answer:

Step-by-step explanation:

Let the cost of Chair be ₹x.

= Cost of Table = ₹ ( x + 400)

A.T.Q.

3 (x + 400) + 5x = 2800

= 3x + 1200 + 5x = 2800

= 8x = 2800 - 1200

= 8x = 1600

= x = 1600/8

= x = 200

Hence,

Cost of Chair = ₹200

Cost of Table = ₹600.

Answer 2

Answer:

Cost of a chair = ₹ 200

Cost of a table =  ₹600

Step-by-step explanation:

Let cost of a  chair  = ₹ x

Cost of  a table = x + 400

3*(x + 400) + 5x = 2800

3x + 3 * 400 + 5x = 2800

8x + 1200 = 2800

8x = 2800 - 1200

8x = 1600

x = 1600/8

x = 200

Cost of a chair = ₹ 200

Cost of a table = 200 + 400 = ₹600
