If P1 and P2 are the populations and R1 and R2are the numbers of representatives of District 1 and District 2, respectively, the ratio of the population to the number of representatives is greater for which of the two districts?
(1) P1> P2
(2) R2 > R1
This is OG 12th edition question . OA IS C

(2) R2 > R1 implies R1/R2 < 1 but no info on populations; NOT sufficient.
Combining (1) and (2), P1/P2 > R1/R2 implies P1 : R1 > P2 : R2; SUFFICIENT.
The correct answer is C.

Yes the OA turns out to be C... try putting as many values of all the 4 things or parameters and you will find the answer...
They all turn out to be giving the same answer as the first ratio (P1/R1) > (P2/R2)
This is always proved in the above given two statements when taken together....
Hence the answer is C and not E....
(1) P1> P2
(2) R2 > R1

Since this problem is restricted to positive integers, the question stem can be rephrased:
Is (P1)(R2) > (P2)(R1)?
Statement 1: P1>P2
Without knowing the relationship between R2 and R1, no way to determine whether (P1)(R2) > (P2)(R1).
Statement 2: R2>R1
Without knowing the relationship between P1 and P2, no way to determine whether (P1)(R2) > (P2)(R1).
Statements 1 and 2 combined:
Since each value on the left side (P1 and R2) is greater than the corresponding value on the right side (P2 and R1), (P1)(R2) > (P2)(R1).
SUFFICIENT.
The correct answer is C.
