GRE- Quantitative Reasoning
QUESTION: 23

Two square rugs R and S, which have a combined area of 20 square feet, are placed on a
rectangular floor whose area is 112 square feet, as shown above. Measured east to west, each
rug is placed the same distance from the other rug as from the nearest east or west edge of the
floor. If the area of rug R is four times the area of rug S, how far apart are the rugs?

A. 3 feet, 4 inches
B. 3 feet
C. 2 feet, 8 inches
D. 2 feet
E. 1 feet, 6 inches

Answer(s): C
Explanation: Rug R must be 4' x 4', and rug S must be 2' x 2'. Also, since the floor's area is 112
and its length is 8, the floor's width = 14, which in turn equals the sum of the following five
lengths (let x = the distance between the two rugs, as well as from each rug to the nearest east
or west edge):
x + 4 + x + 2 + x = 14
3x = 8

2 feet, 8 inches
