(1) Over the past year, the ratio of number of male students to the total number of students increased.
(2) Over the past year, the total number of students increased.

S1 - $$\frac{No. of male students}{Total no. of students}$$ increased
Therefore, either no. of male students increased or total no. of students decreased.
Insufficient.

S2 - Total no. of students increased
No. of Male students could increase or remain constant.
Insufficient.

Combining S1+S2, Ratio increased and total no. of students also increased.
Hence no. of male students must increase.
Sufficient.

Hi

Its possible that the number of male students stayed the same or even decreased slightly, but the number of female students dropped by a big number. That would also cause the ratio of male students : total students to go up.
