Explanation

Putting a number for the number of students in the graduating class. When SUPPLYING for a percentage question, it's helpful to use 100.

Number accepted to college = 80 (80% of 100 OR $$0.80 \times 100 = 80$$)

Number of accepted NOT going to college = 8 (10% of 80 OR $$0.10 \times 80 = 8$$)

Number of accepted going to college = 72 (80 – 8 = 72)

The percentage of graduates going to college is 72 out of 100, or 72%.

Hence Quantity A is greater.

IN Quantity A "The percent of the students in this class 70% who were accepted to college and who will go to college" what does 70% Mean? really disturbing，this can cause the answer to be A since 70% multiply 0.72% (accept and go to college) is farrrrrrrrr below 70%

I THINK 70% who were accepted to college = 0.7*80 = 56
and who will go to college = 72
SO percent = 56/72 = 77.77% WHICH IS GREATER THEN 70%

I think the whole question is wrong! I found the origin

QA: The percent who were accepted and who will go to college QB: 70%

I checked out the stem once again, and it is correct in every word. It is from official power prep software.

Here the best strategy is to read carefully the stem and going step-by-step.

Total students = 100

80 go to college and 20 no.

Of the 80 accepted will not go to the college, which means 8 will not go and we are left with 72 students are accepted and will go to college.

Now 72 is 90 % out of 80.

So, 90% > 70 % (quantity B).
