ayn,

Are you new to GMAT?

-----

O + F + S = 2350, What is O?

S1 => F = S/2 => Insuff

S2 => F+S = 1.5O => Sufficient

Ayn,

The above problem is a Data Sufficiency problem. You are not supposed to use the two statements together and try to solve it. :)

I got B.

Statement I is insuff

Statement II tells us that

First + Second = Orch + .5Orch

Orch + first + second = 2350
Orch + Orch + .5Orch = 2350
2.5Orch = 2350
Orch = 940
So sufficient

:wink:
B
Stem says that :0+F+S =2350

ST1 F= 1/2S

INS O+1/2S+S=2350


ST2 S+F=1.5 O

O+1.5 O = 2350

SYES B
