60% means somevalue less than 100 as we know 151/2 is 75 only
if company has 500 emp
60% means some value more than 100
dual case
A insufficient
2)we may think of supposing in this way 1 male emp and 74 females
but that will voilate 60% case,
when there is
F=M+74
ie M=F-74
Total=M+F
female/total x 100 =60
F/F-74+F x 100 =60
F/F-34 =6/5
5F=6F-204
F=204>100
so B
We can find value of Female which safies both condition
60% of total
female=74+1
only when female greater than 100 (ie 202)
so should be B
Otherwise both condition wont be met

My answer is B
First I simplified the prompt,as I almost always do.
Let the total no of employees =x
Then the question is "is 60/100 *x >100?"
or " x> 1000/6"
or " x> 166.67". The question is talking about integers so the rephrased question becomes " is x >= 167"
See I added equal to because it is allowable as per the equation "x>166.67"
So the real question is " Does the company have 167 or more employees?"
1) x>150.
X could be 160 or 170.
If 160 the answer to the question " Does the company have 167 or more employees?" is NO
If 170 then the answer is YES.
Hence INSUFFICIENT
2) If the number of males employees is m and the number of female employees is f,then f=m+74.
So the total no of employees = m+f = 2m+74.
60/100 (2m+74) = m+74
3/5(2m+74)=m+74
6m+222 = 5m+ 370
m= 148
So total no of employees = 2*148+74= 296+74=370
Since x=370
and we can say in a definitive way whether the no of employees in the company if 167 or more.
This statement is sufficient.
Hence B
