Question

The following data gives the amount of loans (in crores of rupees) disbursed by a bank during some years:

Year	1992	1993	1994	1995	1996
Loan (in crores of rupees)	28	33	55	55	80

(i) Represent the above data with the help of a bar graph.
(ii) With the help of the bar graph, indicate the year in which amount of loan is not increased over that of the preceding year.

Answer 1

Let's draw two mutually perpendicular lines OX and OY.
Along the horizontal line OX, let's mark years; and along the vertical line OY, let's mark loans in crores.
Along the axis OX, let's choose a suitable width for each bar, keeping the gap between the bars the same.
We will now choose a suitable scale to determine the heights of the bars.
Here, let's consider 1 big division = 10 crores of loan
Therefore, the heights of the various bars are as follows:
Height of the bar against the year 1992 $=\frac{28}{10}=2.8$ units.
Heights of the bar against the year 1993 $=\frac{33}{10}=3.3$ units.
Heights of the bar against the year 1994 $=\frac{55}{10}=5.5$ units.
Heights of the bar against the year 1995 $=\frac{55}{10}=5.5$ units.
Heights of the bar against the year 1996 $=\frac{80}{10}=8.0$ units.
Based on the above calculation, the bar graph is as follows:


(ii) The year in which the loan amount has not increased than its previous year is 1995.
Explanation: In the year 1994, 55 crore rupees of loan was disbursed by the bank.
Also, in the year 1995, 55 crore rupees of loan was disbursed by bank.​
