let number of shares be x , bonds be y

from one

x/x+y increased this increase could be from the nominator or the deniminator IE : DENIMINATOR DECREASE WHILE X IS CONSTANT OR THE OPPOSITE OR BOTH CHANGED AT THE SAME TIME ..........insuff

from two

x+y increased , the increase could be from the x or the y factors.........insuff

both together

if the deniminator increase and the nominator remained as is the ratio
decreases

thus sure x increased

X : total number of stocks
Y : total number of bonds

Statement 1: X / ( X + Y ) increased
-------------------------------------------
Insufficient because either could X increased or ( X + Y ) decreased

Statement 2 : ( X + Y ) increased
----------------------------------------
Says nothing .. it's either X or Y or both have increased

Statements 1 and 2 Together :
------------------------------------
When ( X + Y ) increased [denomenator] then the total ratio in statement 1 must decrease; yet, statement 1 indicates that the ratio increases
Therefore, the nomerator ( x ) must have increased !

hope this was helpful and i didn't try to complicate the answer
