Hi all,
This question can be solved in a variety of ways. If you catch the fact that there are only 5 total pounds of fruit, then you can avoid most of the work altogether, since the question asks for the average price per POUND of fruit.
Since none of the other explanations have TESTed VALUES, I'll show you how to use that approach here:
We have...
3 pounds of dried apricots that cost $X per pound and...
2 pounds of prunes that cost $Y per pound.
IF...
X = 3
Y = 4
Then the apricots cost 3($3) = $9
and the prunes cost 2($4) = $8
Total cost = $17 and total weight = 5 pounds, so the correct answer will be 17/5
Answer A: (9+8)/5 = 17/5 This IS a match.
Answer B: (9+8)/(3+4) = 17/7 NOT a match
Answer C: (9+8)/(3)(4) = 17/12 NOT a match
Answer D: 5(9+8) = 85 NOT a match
Answer E: 9 + 8 = 17 NOT a match
Final Answer:
GMAT assassins aren't born, they're made,
Rich
