Stat 2 looks simpler so let's deal with that 1st.

Insuff.: The 42% in the stem could include women. This does not mention anything about the number of women.

Stat. 1
Suff.
Let # of men = X => # of women = 1400-X
.36X+.5(1400-X)=.42*1400

We can solve for X. No further work necessary.

Thanks LM!!! Just goes to show that I need to read the questions more carefully so that I can stop losing careless points.

In this case, I don't think the answer will change though since we can compute the number of women using (1400-X). Statement 1 should be sufficient.
