Question

the cost of 2 tables and 5 chairs is rupees 2300 if a table cost 30 rupees more than a chair find the cost of both chair and table

Answer 1

let the cost of one chair be 'x'
& let cost of one table be 'x+30'
we get,
=> 2(x+30)+5(x)=2300
=> 2x+60+5x=2300
=> 7x=2300-60=2240
=> x=2240/7=320
therefore, x=320
by substituting, we get,
cost of one chair = x = ₹320
cost of one table = x + 30 = 320 + 30 = ₹350
