Question

total cost of a table and a chair is 600. If the cost of the table is twice the cost of the chair, find the cost of each item

Answer 1

let the cost of chair =x
cost of table=2x
atq,x+2x=600
3x=600
x=600/3
x=200
find the values

Answer 2

let the cost of chair be x
cost of table = 2x

therefore

x + 2x = 600

3x = 600

$x = \frac{600}{3}$

x = 200

thus,

cost of chair = x = Rs 200

cost of table =2x = 2 × 200 =Rs 400
