Answer 1

Answer:

40cm is the height of table

Answer 2

Answer:150cm

Step-by-step explanation:Let the height of cat be x cm and the height of tortoise be y cm.

In the first case,

The height of table= (170cm + height of tortoise) -height of cat={ (170+y) -x} cm= (170+y-x) cm

In the second case,

The height of the table=(130cm+height of cat) -height of tortoise={(130+x) -y} cm= (130+x -y) cm

Clearly, 170+y-x=130+x -y

or, 170-130=x-y+x-y

or, 40=2x -2y

or, 40=2(x-y)

or, x -y=20

Hence, the exact height of the table=( 130+ x -y) cm=(130-20) cm= 150cm
