(1) When visiting a house together, George always receives a donation twice as large as the donation received by Barbara.
Just knowing how much money George collects when visiting a house together doesn't give us details who will collect more money overall.
Hence, insufficient.
(2) Barbara averages $2 less per house than George.
We do not know how many house each of them visits, hence knowing that Barbara had a worse average/house doesn't clarify anything
Hence, insufficient.

Combining the information available in both the options, does not clearly give who will collect more money(Option E)

Ans b :

Barbara average house collection is $2 less than George . Its already given both will collect the all houses in community X .So no of houses are same. Therefore Barbara sum would be less and hence B is sufficient

Thanks for pointing our the error. Please find corrected solution

(1) When visiting a house together, George always receives a donation twice as large as the donation received by Barbara.
Just knowing how much money George collects when visiting a house together doesn't give us details who will collect more money overall.
Hence, insufficient.
(2) Barbara averages $2 less per house than George.
The question stem clearly contains, that each of them visit all the houses in Community B.
Since Barbara's average is lesser than George it is clear George collects more money of the two.
Hence, Sufficient. (Option B)

Statement 1: Says "When visiting a house together, George always receives a donation twice as large as the donation received by Barbara". But what if Barbara herself doesn't collect any money or collect some money. So Statement 1 does not gives us any info about whether Barbara collected money or not.

Statement 2: Definitely gives us info to the question asked by telling that Barbara averages $2 less per house than George.

So "B" is correct answer
