Bar graph given below shows the total number of graduate and post graduate employees in five different companies. Table shows the difference between graduate and posts graduate employees.

Companies	Graduate – Post Graduate employees
A	4
B	2
C	36
D	90
E	96

Note – Total Employees = Graduate + Post Graduate Employees
Graduate employees are more than Post Graduate Employees

In C, total females who are graduated is 50, Number of males who are graduated is 20 more than females who are post graduated. Males who are post graduated in C are what percentage more/ less than that of post graduated employees in D?

Correct Answer: 38.18%

To solve this problem, we will first extract the total number of employees for companies C and D from the provided bar graph:
- For Company C, the height of the bar corresponds to $226$ employees.
- For Company D, the height of the bar corresponds to $200$ employees.

We are given that:
Total Employees = Graduate (G) + Post Graduate (PG) Employees
Graduate Employees > Post Graduate Employees (G > PG)

Step 1: Calculate the number of post-graduate employees in Company D
From the table, the difference between Graduate and Post Graduate employees (G - PG) for Company D is $90$.
We have the system of linear equations:
$G_D+{\mathrm{PG}}_D=200$
$G_D-{\mathrm{PG}}_D=90$
Subtracting the second equation from the first:
$2·{\mathrm{PG}}_D=200-90=110$
${\mathrm{PG}}_D=55$
So, the total number of post-graduate employees in Company D is $55$.

Step 2: Calculate the number of graduate and post-graduate employees in Company C
From the table, the difference (G - PG) for Company C is $36$.
We set up the equations:
$G_C+{\mathrm{PG}}_C=226$
$G_C-{\mathrm{PG}}_C=36$
Adding these equations gives:
$2·G_C=262\Rightarrow G_C=131$
Subtracting them gives:
$2·{\mathrm{PG}}_C=190\Rightarrow {\mathrm{PG}}_C=95$

Step 3: Analyze the gender distribution of employees in Company C
We are given that:
- Total females who are graduated in C = $50$
Therefore, the number of males who are graduated in C is:
$\text{Graduate Males}=G_C-\text{Graduate Females}=131-50=81$

We are also told that the number of males who are graduated is $20$ more than females who are post-graduated:
$\text{Graduate Males}=\text{Post Graduate Females}+20$
$81=\text{Post Graduate Females}+20\Rightarrow \text{Post Graduate Females}=61$

Now we can find the number of males who are post-graduated in C:
$\text{Post Graduate Males in C}={\mathrm{PG}}_C-\text{Post Graduate Females}=95-61=34$

Step 4: Find the required percentage
We need to determine what percentage more/less the post-graduated males in C ($34$) are compared to the post-graduated employees in D ($55$).
Since $34<55$, they are less.
Percentage less = $\frac{55-34}{55}\times 100\%=\frac{21}{55}\times 100\%=38.18\%$
