Official Solution:

Mary spent 64 percent of her salary on food (including meat) and 16% of her salary on meat. What percent of the salary spent on food were not spent on meat?

A. $$16%$$
B. $$25%$$
C. $$32%$$
D. $$48%$$
E. $$75%$$

64% of her salary on food;

16% of her salary on meat;

So, we have that 64%-16%=48% was spent on food but not on meat, thus $$\frac{48}{64}=\frac{3}{4}=75%$$ of the salary spent on food were not spent on meat.

I think something's wrong here. I got the answer right and market it right but the software has marked the OA as wrong

I think this is a poor-quality question and I agree with explanation. poor question wording. makes it seem as if there were two. a 64% which had meat and non meat, then another 16% that had only meat.

Sorry, but I don't see any ambiguity in the question.

Hi

The question clearly says "64% on food (including meat) and 16% on meat". This means out of Rs 100, Rs 64 spent on food and out of those 64, Rs 16 spent on meat. So Rs (64-16) = Rs 48 spent on food but not on meat.

Required percentage = 48/64 * 100

Assign 100% = $1,000 64% food W(meat) =$640
16 % only meat = $160$640 - $160 =$480

$480/$640 = 75%

75% not spent on meat

I agree, I personally was unable to solve the problem due to the wording. I understood the problem to be an overlapping sets question based on the wording. As a native english speaker, I understood it as 64% of her salary was spent on food, some of which was meat. Taking the same salary into consideration, 16% of it was spent on just meat.

My only goal is to contribute to the community from the which I have taken so much, and ultimately help make the GMAT Club forums a better place to learn. In my posts, I share my learning outcomes by verbalizing how I solved problems, and hope that the added perspective can help anyone achieve an 'ah-hah' moment.

Sometimes it takes a concept being explained in 15 different ways to achieve an 'ah hah' breakthrough moment and I am here to contribute one, of hopefully many, unique perspectives. I do not encourage or participate in posts that simply state "that was easy", or "relevant, out of scope, correct". I find that people - myself included - often have a difficult time truly understanding the fact that in CR/RC questions, there will be one very definitively black and white correct answer, just a there is in Quant. As a result, my posts are exclusively focused on CR and RC. There is no such thing as a 'kinda right' question and because of this, I contribute detailed posts on how I came to my answer in hopes that it will connect with someone.

Wishing everyone all the best
