5 unit height.

Answer 2

Concept:

Bar graph contains rectangular bars which is used to represent categorical data. The height of the bars are proportional to the values they represent.

The unitary method is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.

Given:

In a bar graph a column of 8 unit height is drawn to represent 40 children then to represent 25 children

Find:

what should be the height of

the column?

14 cm

2 8 cm

3 6 cm

4 5 cm

Solution:

Using unitary method,

40 children =8cm

⇒1 children = 8/40 cm

⇒25 children= 0.2 x 25 cm

                      = 5 cm

So the answer is option 4, 5 cm
