Draw a Bar graph representing the given information.

Answer 1

As per the information given in table, we will make a bar graph

Let us select the scale first.

let $1cm=50$ companies

Now we shall calculate the length of the bars for various years.

For $1957=50÷50=1$

For $1962=50÷50=1$

For $1967=75÷50=1.5$

For $1972=100÷50=2$

For $1977=250÷50=5$

For $1982=350÷50=7$

For $1987=400÷50=8$

Therefore, the required bar graph is:
