(2) The broker charged $3,000 as the brokerage.

Question : The brokerage was what percent of the value of the property?

Statement 1 : The property values $1.8 million.

The brokerage percentage can't be calculated unless we also know the amount of brokerage on this property hence

NOT SUFFICIENT

Statement 2 : The broker charged $3,000 as the brokerage

But we don't know the worth of the property on which th ebrokerage is charged hence

NOT SUFFICIENT

Combining the two statements

Property Worth = $1.8 million
Brokerage = $3000

Now we can calculate the brokerage as percentage of property worth (= 3000*100/1.8*1000000 = 0.167%) hence

SUFFICIENT

Answer: Option C

DavidTutorexamPAL · Answer

The answer is C.  
This question can be easily solved using the logical approach - checking whether we have enough data, without trying to solve. 
the question describes an equation with three variables - the property value, the fixed percent, and the actual brokerage fee (Value*(fixed percent) = brokerage fee). To find one variable (the percent), we must have the other two. 
(1) and (2) are clearly both insufficient on their own, as they each only give us one of the variables we need. 
 Combined, however, we have two variables - enough to find the third! the answer is (C).

Yes the answer sure seems to be C. 
But how can we say that the brokerage that was charged was on the property. Since brokerage is a percentage on the property, there is definitely a possibility that the brokerage 3000 is not on the property 1.8 million.
Hence I feel the answer should be E.
Perhaps  Bunuel  can clear out this confusion in the question to make it unambigious
Or correct me if I am not getting something.

let the brokerage fee be  A  the percentage of brokerage would be  B  and the value of property be  C.

A = \frac{B}{100} * C

I cannot find B without knowing both A and C.

Hence 1) and 2) are insufficient alone.

Together it is sufficient.

C
