Question : Directions: The subjective number of applicants for the years 2008 and 2009 in a college is given in the following chart. Study the graph and answer the questions.

The subject for which growth of demand is minimum is:

Option 1: Statistics

Option 2: Zoology

Option 3: Botany

Option 4: Microbiology

Correct Answer: Botany

Solution : According to the given bar graph:
Number of applicants for the year 2008 in Zoology = 854
The number of applicants for the year 2009 in Zoology = 932
Difference = 932 – 854 = 78
Percentage increased = $\frac{\text{Difference}}{\text{Applicants in 2008}}\times100$
= $\frac{78}{854}\times100$
= 9.13%
Number of applicants for the year 2008 in Statistics = 435
The number of applicants for the year 2009 in Statistics = 482
Difference = 482 – 435 = 47
Percentage increased = $\frac{\text{Difference}}{\text{Applicants in 2008}}\times100$
= $\frac{47}{435}\times100$
= 10.80%
Number of applicants for the year 2008 in Botany = 265
The number of applicants for the year 2009 in Botany = 248
Difference = 265 – 248 = 17
Percentage increased = $\frac{\text{Difference}}{\text{Applicants in 2008}}\times100$
= $\frac{17}{248}\times100$
= 6.85%
Number of applicants for the year 2008 in Microbiology = 365
The number of applicants for the year 2009 in Microbiology = 406
Difference = 406 – 365 = 41
Percentage increased = $\frac{\text{Difference}}{\text{Applicants in 2008}}\times100$
= $\frac{41}{365}\times100$
= 11.32%
The lowest is Botany.
Hence, the correct answer is Botany.
