Hi:
Let me try this graphically... ok so the stem is telling us that m >100
stat #1 --- 0.15s = 72 ==> s = 480. It doesn't say anything about actual size of m (only says that m >100)
stat #2 --- n=252. no way to know s or m
stat 1+2 --- n=252 and s = 480 and b = 72. Again no info on *actual* value of m

Hence E

BTW, I have seen that the line diagrams work better for me than Venn diagrams because they allow me to visualize NONE condition in the same picture (and I can draw line better than a circle )

I think the best way to look at this question is through a chart in which we have the columns sales nonsales on the top and management non management along the left side going up and down so that we can plug in the information given easily and we can see what information is missing and what we need. From statement 1 we can come up with a total number for sales people with management non management (480). For management the word at "least" gives us too much to work with: meaning we can make salespeople greater than management and management greater than salespeople....eliminate a and d

Statement 2 doesn't do anything... Information there is useless and combining the two does not yield us a concrete answer .... Eliminate answer choice b and c

choose e

at least 100 of E (employees)=M
is S>M ?

stmt 1- 0.15E=S+M (both) =72 E=480 insuff

stmt2- N=252 so what?! insuff

stmt 1 +stmt 2 - atleast 100+OnlyS-2*72+252=480
atleast 100+OnlyS=372
if M=100 then S>M
if M=300 then S<M
so, insuff

(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.

Let:
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.

If 15% is 72, we know total employees(t) as 480. Is it not?

Its 15% of sales staff. So 480 is the total no of sales people. Still does not give us the total no of people hence management could be anything equal to or greater than 100 for ex... 100 or 200 or 300 and so forth..

QED (E)

E the answer.

If we know that 72 represents 15% of sales staff, doesn't that tell us that 72 represent 85% of the Management staff?

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.

IMO: E
St. 1
We can get n from st. 1, but can not know the number of employees with mgt and sales experience. Bcz. employees with mgt may be equal to or more than 100. NS
St. 2 Clearly NS
1 and 2 together also don't work.
