Use the figures given below to find how tall the table is -

180

220

{

}

SOLUTION!

Let t, c and r represent the heights of the table, cat and rat respectively.

From the first diagram

c+t-r=220

From the second diagram

r+t-c=180

Adding these 2 equations and simplifying we get t=200

Therefore the height of the table is 200.
