Answer 1

Answer:

let cost of 1 chair=rs.x

let cost of 1 table=rs.y

Step-by-step explanation:

given=

2x+2y=4800

2(x+y)=4800

x+y=2400 ------(1)

y=1200+x

y-x=1200 -------(2)

adding (1) and (2)

2y=3600

y=1800

therefore,

x=1800-1200=600

CP of 12 chair= 600 x 12

                      =7200

no of tables which can be bought for 7200=

7200/1800=4 tables
