From statement 1: we don't get any information about Female or male? hence it's not sufficient.

From statement 2: it directly says 1/3rd of Democrats i.e. 600 and 1/2 of the republicans i.e.1500 are female!

Hence it's B!

From Option 2 you can directly hit the answer.

B

Given, D = 1800, R = 3000
Let D1 = voted for K, D2 = voted against K
Let R1 = voted for K, R2 = voted against K

from 1) D1 = (3/4)D, R1 = (2/3)R
we cannot tell the no. of females voted for K from this eq.
Hence insufficient

from 2) females voted for K = (1/3)D1 + (1/2)R1
we do not know the values of D1 and R1.
Hence insufficient

Hence 1 & 2 will be sufficient => C
