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

$5x + 4y = 1560$

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

$5y + 300 + 4y = 1560$

$9y + 300 = 1560$

$9y = 1260$

$y = 1260/9$

$y = 140$

$x = 140 + 60 = 200$

Answer 2

let a table be x rs and chair be y rs.
then
5x+4y=1560
but x=y+60
then,
5(y+60)+4y=1560
5y+300+4y=1560
9y=1260
y=140 rs.

x=y+60
x=140+60
x=200 rs.
so cost of table is 200 and cost of chair is 140.
