This is OG 12th edition question . OA IS C
[spoiler]Please assist me in knowing how both the statements are useful? i am able to make out that statements individually are NOT sufficient.[/spoiler]
the explanation given in OG is very confusing
thanks
Is P1/R1 > P2/R2?
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.
