What is the ratio of the number of cups of flour to the number of cups of sugar required in a certain cake recipe?

(1) The number of cups of flour required in the recipe is 250% of the number of cups of sugar required in the recipe
(2) 1 1/2 more cups of flour than cups of sugar are required in the recipe.

I got the wrong answer and I now know the correct answer but need the rationale - could someone tell me the answer and the rationale behind the answer? Thanks. I'll post the OA later.

The question is asking -- what is f/s ?

(1) f = 250%(s) = (250*s)/100 ------ f/s = 5/2 ---- sufficient
(2) f = s + s(1 1/2) = s + (3*s)/2 = (5*s)/2 ------ f/s = 5/2 ---- sufficient

answer is D ?

Answer should be A.

stmt2 says, f = s + 3/2 and hence, f/s cannot be determinded.

The worst part is F/S from (1) and your misinterpreted (2) arrives at 5.2 leaving you no room for second thought. after I saw D, I thought I dinged the Q by choosing A

Tejal,

You might want to re-read the stmt-2. 3/2 more cups is different from 3/2 times more cups. when it says times, you can take s + s(3/2) but it's just a cup and half over s so s + 3/2.

Infact, I too got the answer wrong, thought it was D and later figured out what was wrong, with my reading!!!!

We require Cf/Cs = ?

1) Cf = 250/100 (Cs)
Cf = 5/2 Cs SUFF
2) Cf - Cs = 3/2 (Putting stmt this way removes the confusion)
Clearly NOT sufficient

Answer A clearly. B means that if one is 3 then other is 4.5; if one is 7 then other is 8.5. Ratio is different hence not suff

Yes, (2) translates: F = S + 3/2.

Yes. I also chose D at first but in retrospect the question is easy if you read the word problem correctly.

Statement 1 says F = S multiplied by something, because it states '250% of y' of = times = *
Statement 2 says F = S + 1.5 indeed, as the wording 'x more ... than y' = y + x

The first statement thus gives you a ratio (sufficient), the second does not as F could equal 5.5 and S 4 cups. Or F could equal 7 and S 5.5 cups which give different ratios.

thus the answer is A.
