Question

the total cost of 5 tables and 4 chair is rupees 1560 if a table cost of rupees 60 more than the cost of a chair find the cost of one table and one chair​

Answer 1

Answer:

Let the cost of table be 'x' and chair be 'y'

5x + 4y = 15605x+4y=1560

5(y+60) + 4y = 15605(y+60)+4y=1560

5y + 300 + 4y = 15605y+300+4y=1560

9y + 300 = 15609y+300=1560

9y = 12609y=1260

y = 1260/9y=1260/9

y = 140y=140

x = 140 + 60 = 200x=140+60=200
