Question 97 – “Of the following…”

OG Explanation is fine.

Question 98 – “Which of the following…”

OG Explanation is fine.   The easiest way to do this problem is to recognize since x and y are positive, x cannot be divisible by x+y because x cannot be divisible by a number bigger than itself.    The same logic applies for y.

Question 99 – “If a, b,….”

OG Explanation is fine.    Notice that if the numerator is equal to the denominator of a fraction, then that fraction equals 1.     So we could rephrase the question: for answer choices A through E, does the numerator equal the denominator?

Choice A: Does a-b=c?  No, because a+b=c and b is nonzero.

Choice B: Does a-c=b?  No, because a+b=c, which means a – c = – b

Choice C: Does b-c=a?  No, b-c = – a

Choice D: Does b-a=c?  No, because a+b=c, so b+a=c and a is nonzero.

Choice E: Ford c-b=a?  Yes, since a+b=c  then  a=c-b

The answer is E.

Question 100 – “Last year Carlos…”

OG Explanation is fine.   Alternatively, we could pick numbers.   Supposed he earned $100 last year; then he saved $10.   This year he saved 12% of $105.   12% of $105 is $12.60.

$12.60 is a 126% of $10.00.    Therefore, the answer is C.
