(B) for me

Stat 1No information about Male and Female...

INSUFF.

Stat 2Take the total amount of students equal to 100.

Let be:

> M : the number of male (actually it's the percentage we are looking for)

> F : the number of female

We have:

o M + F = 100

o 0.72*M + 0.8*F = 75

2 equations and 2 unknown variables.

SUFF.

Exactly what I had written down. I figured b/c we know .72M+.8F=75

And .28M+.2F=25 and M+F=100

Then i figured B was sufficient b/c its not looking for any real numbers here, just fraction/percentage.
