Question

Find the height of the table.

Answer 1

Let height of table is x
height of cat is y
height of turtle is z .

case 1 :- height of cat + height of table - height of turtle = 170cm
y + x - z = 170 ........(1)

case 2 :- height of turtle + height of table - height of cat = 130cm
z + x - y = 130........(2)

adding equations (1) and (2),

y + x - z + z + x - y = 170 + 130

2x = 300 => x = 150

hence, height of table is 150cm.

Answer 2

Hey there!

Let the heights of table, cat, turtle be x, y, z respectively

Now from the above figures ,

x + y - z = 170 cm

and,

x + z - y = 130 cm


adding both equations,

we get,

x + y - z + x +z - y = 300 cm

2x = 300 cm

x = 150 cm


Therefore, Height of the table is 150cm
