Hi Guys, I have doubts in solving/understanding this basic problem:

Over a period, did the number of stocks in Fredy's portfolio increased?

a) Over the period, the ratio of the number of sotck to the thotal number of stocks and bonds in Fredy's portfolio increased.

b) Over the period, the total number of stocks and bonds in Fredy's portfolio increased.

Could you pls. suggest a way to solve this, may be picking numbers for both stocks and bonds? many tks. in advance, lw

x = number of stocks
y = number of bonds

1) x/x+y increased. may be y decreased so x/x+y increased.
2) x+y increased. tells nothing that x increased or not. May be just y increased.

Combined.
x+y increased and also x/x+y increased that means x also increased. Therefore C.
