The combined area of the front and back of a rectangular sheet of paper measuring 11 inches by 17 inches = 2*17*11 sq inches

The combined area of the front and back of a rectangular sheet of paper measuring 8.5 inches by 17 inches = 2*8.5*11 sq inches

So, the required percentage increase = [(2*17*11 – 2*8.5*11)/(2*8.5*11)]*100% = 100%

Correct answer: C

Hope this helps!

Solution:

We see that one of the dimensions of the two rectangles is equal while the other dimension of the larger rectangle is twice that of the smaller rectangle. Therefore, the combined area s of the front and back of the larger rectangular sheet is twice that of the smaller rectangular sheet, i.e., 100% greater than that of the smaller rectangular sheet.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
