Question

The investment (in ten crores of rupees) of Life Insurance Corporation of India in different sectors are given below:

SECTORS	INVESTMENT (in ten crores of rupees)
Central Government Securities	45
State Government Securities	11
Securities guaranteed by the Government	23
Private Sectors	18
Socially Oriented Sectors (Plan)	46
Socially Oriented Sectors (Non-Plan)	11

Represent the above data with the help of a bar graph.

Answer 1

Hint: Here, we will make the horizontal and vertical axes represent the sectors and the investment in ten Crores of rupees respectively. Then we will draw 6 bars of different lengths given in the table, so at first, we will mark 6 points in the horizontal axis at equal distances and erect rectangles of the same width at these points.

Complete step by step answer:

To represent the given data by a vertical bar graph, we first draw horizontal and vertical axes.
Let us now consider that the horizontal and vertical axes represent the sectors and the investment in ten Crores of rupees respectively.
We have to draw 6 bars of different lengths given in the table.
At first, we will mark 6 points in the horizontal axis at equal distances and erect rectangles of the same width at these points.
So, we know the heights of the rectangles are proportional to the investments of Life Insurance Corporation of India.
We will now draw the vertical bar graph of the given data where 1 unit in the vertical axis represents 10.

Note: Students need to know that a bar graph can be defined as a chart or a graphical representation of data, quantities, or numbers using bars or strips. So we use these graphs to compare and contrast numbers, frequencies, or other measures of distinct categories of data. We should know that what is asked in question properly, like when we need to mark a bar graph of one sector to mark the investment for each. So be careful with that.
