At least 100 employees in a certain company have management
experience. If 15 percent of the employees in the company who
have sales experience also have management experience, do
more employees have sales experience than management
experience?
(1) 72 employees in the company have both sales
experience and management experience.
(2) 252 employees in the company have neither sales
experience nor management experience.
How do you evaluate statement 1? I had 15%(S)= 72 where S equal number of with sales experience. OA seems to suggest that its 15%(total)=72 where 72 equal having both. What is the correct interpretation?

The question clearly mentions "15 percent of the employees in the company who have sales experience also have management experience" and statement 1 says, "72 employees in the company have both sales experience and management experience. ".
Therefore, number of employees having both experience = 72
=> 15% of employees with sales experience = 72
=> Number of employees with sales experience = 72/(0.15) = 480

E is the correct answer, isnt it?
At first glance it seems that you can find certain numbers, but the condition "at least" gives us many possible answers, which include both situations: more employees w/sales experience and more employees w/managerial experience.
Therefore both are insufficient.

The question is simply asking which number is greater, # of employees with sales experience or # with management experience?
And we are told:
Employees with management experience: 100
Employees with sales experience: N and .15N also have management experience.
STATEMENT 1
72 employees have both sales and management experience. Therefore, 72 = .15N and N = 480.
Thus, there are more employees with Sales experience than with management experience. Sufficient.
STATEMENT 2
252 employees have neither sales nor management experience... This is superfluous info. Therefore, insufficient.
I believe the answer is A.
OA?

Read the problem statement properly.aleph777 wrote:...

There is a "At least" term in the very beginning of the problem.

OA must be E.
Since it says "at least"

I am using both options
I have got total emp = 480 from 72/0.15
it was told neither is 252 so P(S)+P(M)+P(MuS) = 480 - 252 = 228
Then from A again P(MuS) = 72 therefore P(S)+p(M) = 156
P(M) is atleast 100 and Here we need to find if P(S) > P(M)
I am getting answer as C ... what is the wrong I am doing how is it E.

experience?
(1) 72 employees in the company have both sales

(2) 252 employees in the company have neither sales

m = management experience
s = sales experience
b = both management and sales experience
n = neither management nor sales experience
t = total employees
Question: Is s>m?
What we know:
m≥100.
b = .15s
Statement 1: b = 72
.15s = 72
s = 72/(.15) = 480.
If m=100, then s>m
If m=1000, then s<m.
Insufficient.
Statement 2: n = 252
No way to determine whether s>m.
Insufficient.
Statements 1 and 2 together:
Combining the statements, s = 480 and n = 252, but we still don't know the value of m or t.
If m=100, then s>m.
If m=1000, then s<m.
Insufficient.
The correct answer is E.

The keywords are as highlighted:
"At least 100 employees in a certain company have management experience. If 15 percent of the employees in the company who have sales experience also have management experience, do more employees have sales experience than management experience? "
So 15% of sales employees also have mgmt. experience. So statement only tells us the total SALES.
Total MGMT is still unknown - stem only tells us that it is >100 and statements don't give any more details on MGMT employees.
Hence E
