11.11%

Solution :

The correct answer is 11.11%.

Let the number of lab assistants in colleges A, B, and C be represented by LA, LB, and LC, and the number of professors be represented by PA, PB, and PC respectively.

From the given information, we can set up the following steps to find the values:

Step 1: Find the total staff in college C
We are given that the total staff (lab assistants + professors) in college A is 82:
LA+PA=82
The total staff in college C is 24 more than that in college A:
Total staff in C=82+24=106
So,
LC+PC=106

Step 2: Find the number of lab assistants and professors in college C
For college C, the total lab assistants is 6 less than the total professors:
LC=PC-6
PC=LC+6
Substituting this value into the total staff equation for C:
LC+(LC+6)=106
2LC+6=106
2LC=100
LC=50
Therefore, the number of professors in college C is:
PC=50+6=56

Step 3: Find the number of lab assistants in college B
The lab assistants in college B is 4 more than the lab assistants in C:
LB=LC+4=50+4=54

Step 4: Find the number of professors in college A
The number of professors in college A is 44 less than the lab assistants in college B:
PA=LB-44=54-44=10

Step 5: Find the number of professors in college B
The total number of professors in all three colleges is 102:
PA+PB+PC=102
Substituting the known values:
10+PB+56=102
66+PB=102
PB=36

Step 6: Find the total staff in college B
The total staff in college B is the sum of its lab assistants and professors:
Total staff in B=LB+PB=54+36=90

Step 7: Calculate the required percentage
We need to find what percentage of the total staff in B is the total professors in A:
Percentage=(PATotal staff in B)×100
Percentage=(1090)×100=1009%11.11%
