C

s - the number of shares of stock
b - the number of bonds

1. [s/(s+b)]↑: it is possible when s↑ and b=constant or b↑ and s=constant. INSUFF.
2.(s+b)↑: it is possible when s↑ and b=constant or b↑ and s=constant. INSUFF.
1&2. [s/(s+b)↑]↑: (s+b)↑, so is s↑ to satisfy first condition

1: Could have the shares increase OR the number of bonds could have decreased. Insuff.

2: TOTAL increased. Shares could have increased or decreased. Why? b/c bonds could have increased, thus increasing the total.

Together. B/c the total increases and the ratio of stocks to bonds increases, we can't have the scenario where bonds increase and stocks decrease or the ratio of stocks to bonds would not increase.

Therefore C.

I think it is B, because increased amount in second statement is related particularly to shares not bonds.

a/a+b increases only when a increases and b remains constant or both a and b increases. only C tells us that fact.
