GMAT Quantitative Reasoning Practice Test 1

Question : 34 of 100

Marks: +1, -0

X percent of the rooms are suits, and

Y

percent of the rooms are painted light blue?
Which of the following best represents the least percentage of the light blue painted suits?

Solution:

X + Y − 100

shows us the difference between the sum of the percentages and 100 percent. If

X + Y > 100

, this percent must be subtracted from the sum

X + Y

in order to get 100 percent. Sum of sets minus the total equals the congruence.
