Let the cost of 1 chair be X
then
the cost of 1 table = X + 30
the cost of 2 tables and 5 chairs = 2(X+30) + 5x
the cost is given 2300
2(X+30) + 5x = 2300
2x + 60 + 5x = 2300
2x +5x = 2300 - 60
7x = 2240
x = 2240/7
x = 320
The cost of 1 table is 320 + 30 = ₹360
The cost of 1 chair is ₹320
then
the cost of 1 table = X + 30
the cost of 2 tables and 5 chairs = 2(X+30) + 5x
the cost is given 2300
2(X+30) + 5x = 2300
2x + 60 + 5x = 2300
2x +5x = 2300 - 60
7x = 2240
x = 2240/7
x = 320
The cost of 1 table is 320 + 30 = ₹360
The cost of 1 chair is ₹320
