Question

The line graph shows the income of the RBI department. In which of the years, was the annual income maximum?

(a) 1996
(b) 1999
(c) 2000
(d) 2001

Answer 1

Hint: We have given a line graph and we are asked to find the year in which the annual income of the RBI department was maximum. To find the year, see the topmost point of the line graph and then see that the year corresponds to the topmost point in the line graph.

Complete step-by-step solution:
The line graph given in the above problem is as follows:

In the above line graph, you can see various diamonds which are exhibiting year and the corresponding annual income in that year. Now, we are asked to find the year in which the annual income was maximum which we are going to find by looking at the diamond which is at the maximum height from all the diamonds given above then the year corresponding to that diamond is the year in which the maximum annual income happened.
In the below figure, we have shown the highest diamond by an arrow.

Now, the year corresponding to this diamond that we have marked with an arrow is 1999.
From the above discussion, we have found that the year in which the annual income was maximum was in 1999.
Hence, the correct option is (b).

Note: There is a possibility that you might mistakenly pick the wrong highest diamond so to avoid such mistakes drop the perpendicular from each of the diamonds onto the horizontal axis and then the diamond which has the longest line is the diamond of the greatest height.

Now, you can see that the line joining the diamond and the year 1999 is the longest line.
