OA D Source: GMAT Prep Let's take each statement one by one. 1) The length of a side of square S is 10% greater than the length of a side of square T. Say the length of the side of the square T is x unit; thus, the length of the side of the square S would be (x + 10% of x = 1.1x) unit => Area of the square T = x*x = x^2 => Area of the square S = 1.1x*1.2x = 1.21x^2 Thus, the area of square region S is 21 percent greater than the area of square region T. Sufficient. 2) The length of a side of square S is 22 and the length of a side of square T is 20. => Area of the square T = 20*20 = 400 => Area of the square S = 22*22 = 484 Thus, the area of square region S is [(484 - 400)/400)*100%] = 21 percent greater than the area of square region T. Sufficient. The correct answer: D Hope this helps! -Jay _________________ Manhattan Review Locations: Manhattan Review Madhapur | GMAT Prep Kukatpally | GRE Prep Jayanagar | Tarnaka GRE Coaching | and many more...
