Answer 2

Step-by-step explanation:

Let the number of tables be x and the number of chairs be y

Therefore,

5x + 7y = 13000............ (1)

According to second condition,

2y = 2400

Therefore,

y = 1200

Put y=1200 in (1)

5x + 7(1200)= 13000

5x + 8400 = 13000

5x = 13000 - 8400

5x = 4600

x=4600/5

x=920

Therefore, cost of chair=₹920
