st 1)company has 151 empViper83 wrote:If 60 percent of the employees at Company X are female, does Company X have more than 100 female employees?
(1) Company X has more than 150 employees.
(2) Company X has 74 more female employees than male employees.
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
