Question

height of the table.

Answer 1

HT is Height of Table

Ht is height of Tortoise

HC is height of Cat

HT + Ht - HC = 170

HT + HC - Ht = 130

Solving equations by elementary method

2HT = 300

HT = 150

So height of table is 150cm

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.
