Three rugs have a combined area of 200 square meters. By overlapping the rugs to cover floor area of 138 square meters, the area that is covered by exactly two layers of rug is 24 square meters. What is the area that is covered with three layers of rug ?
Choose the correct choice from the following options:
A) 18 square meters  B) 19 square meters  C) 24 square meters  D) 28 square meters  E) 30 square meters
Total = Rug1 + Rug2 + Rug3 - {overlap of exactly 2 rugs} - 2*{overlap of exactly 3 rugs}   138 = 200 - 24 - 2*{overlap of exactly 2 rugs} --&gt; {overlap of exactly 3 rugs} = 19.   Answer: 19 square meters.
