Answer 1

Step-by-step explanation:

let,the cost of chair be x Rs

the cost of table is y RS.

a/c to condition 1

x+y=1500........................1

a/c to condition 2

y=4x

-4x+y=0

4x-y=0..................2

adding eq 1 and 2

x+y=1500......1

+4x-y=0.......2

_____________

5x=1500

x=1500/5

x=300

put x=300 in eq 1

x+y=1500

300+y=1500

y=1500-300

y=1200

there fore, cost of chair is 300RS

cost of table is 1200Rs
