Question

What is the height of table cat and tortoies 170- 130

Answer 1

Picture (1) -

Table + cat - turtle = 170 cm --------- ( 1 )

Picture (2) -

Table - cat + turtle = 130 cm ---------- ( 2 )

Adding Two Equations we get -

2 Tables = 170 + 130

2 Tables = 300

1 Table = 300 ÷ 2 = 150 cm .

1 Table = 150 cm .


Hence :

$\bold{Height \: of \: the \: table \: is \: 150 \: cm}$

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.
