Question

What's the height of the table (25 points for answering)

Answer 1

From diagram 1:

Table + Cat - Tortoise = 170 cm ----------------- [ 1 ]

From diagram 2:

Table - Cat + Tortoise = 130 cm ----------------- [ 2 ]

Add the two equation [ 1 ] and [ 2 ] :

2 Tables = 300 cm

1 Table = 300 ÷ 2

1 Table = 150 cm

Answer: The table is 150 cm tall.

Answer 2

Considering the figures,

Inferences from the first picture:

Height of the table + cat - tortoise = 170

Inferences from the second picture:

Height of the table - cat + tortoise = 130  

Let us consider the height of the table, cat and tortoise to be x, y and z respectively.

Hence we get,

x+y-z=170  

x-y+z=130

Equating both the equations:

By addition,

x+y-z=170  

x-y+z=130

We get,

Height of two tables = 170 + 130

Height of two tables  = 300 cm

Therefore,

Height of one Table = 300 ÷ 2  = 150 cm

Hence, the height of the table is 150 cm.

The distance between the cat and the tortoise cannot be determined with the data available.
