Answer 10

Well I finally got back to the computer.

To make it easy, let's say John earns $120 and Mary earns $100
20 % of 100 (.2 x 100) = $20. So, John earns 20% more than Mary.
In this first comparison, this is true.

When we make the second comparison (Mary earns 20% less than John or 20% of $120 less) this does NOT hold true because we first based based the percentage on Mary's earnings and the second percentage is based on John's earnings.

For the second comparison we have to change the percentage.
$120 minus what percentage of $120 equals 100?
120 - (120 * x) = 100
20 = 120 * x
x= 20 / 120
x = .1666666666... or 16.66%
So, 120 -(.16666666*120) = 100

Basically, Mary earns 16.66666% less than John.
Or to state it another way Mary earns (100% - 16.666666%) or 83.33333% less than John. Note that (50/3) per cent = 16.6666666%

So, the correct choice to make is A
