Answer 1

Answer:

150 cm

Step-by-step explanation:

let the height of cat be x and height of turtle be y

fig 1

170 cm= height of table in fig. 1 + height of cat - height of turtle

height of table in fig. 1 = 170 cm - height of cat + height of turtle

height of table in fig. 1 = 170 cm - x + y                  (1)

fig. 2

130 cm= height of table in fig. 2 + height of turtle - height of cat

height of table in fig. 2= 130 cm - height of turtle + height of cat

height of table in fig. 2= 130 cm - y + x                   (2)

in 1 and 2, since LHS are equal, RHS are equal

170 cm - x + y = 130 cm - y + x

170-130 = 2x -2y

40 = 2x -2y

40 = 2(x-y)

x-y = 20                (3)

using 3 in 2, we get

height of table in fig. 2= 130 cm +x-y

height of table in fig. 2= 130 cm +20

height of table in fig. 2= 150 cm
