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 company X, the total employees are average number of employees in A, C and E. The ratio of graduate employees in A and X is 1:1. Find the ratio of post graduate employees in X and graduate employees in E?

From the given bar graph, we can determine the total number of employees for each company:
Total employees in Company A = 220
Total employees in Company C = 224
Total employees in Company E = 204

Let the number of graduate employees and post-graduate employees in any company be represented by $G$ and $P$ respectively. According to the problem statement, $G>P$.

Step 1: Calculate the graduate and post-graduate employees in Company A
We are given:
$G_A+P_A=220$
$G_A-P_A=4$
Adding these two equations:
$2G_A=224\Rightarrow G_A=112$
Thus, the number of graduate employees in Company A is 112.

Step 2: Calculate the graduate and post-graduate employees in Company E
We are given:
$G_E+P_E=204$
$G_E-P_E=96$
Adding these two equations:
$2G_E=300\Rightarrow G_E=150$
Thus, the number of graduate employees in Company E is 150.

Step 3: Calculate the total employees in Company X
The total number of employees in Company X is the average of the total employees in Companies A, C, and E:
${\text{Total}}_X=\frac{220+224+204}{3}=\frac{648}{3}=216$

Step 4: Find the graduate and post-graduate employees in Company X
We are given that the ratio of graduate employees in A and X is 1:1:
$G_X=G_A=112$
So, the number of post-graduate employees in Company X is:
$P_X={\text{Total}}_X-G_X=216-112=104$

Step 5: Find the ratio of post-graduate employees in X to graduate employees in E
The required ratio is:
$P_X:G_E=104:150=52:75$

Therefore, the correct option is 52:75.
