total price change ; 30+1.2+3.1-4+2-0.2 = 32.1
so % change = 32.1-30/30 = 7%
IMO D

(A) 3.2% (B) 4% (C) 5.6% (D) 7% (E) 10% The value of the stock after 5 days is: 30 + 1.2 + 3.1 - 4 + 2 - 0.2 30 + 6.3 - 4.2 = 36.3 - 4.2 = 32.1 We use the percent change formula: Percent Change = (New - Old)/Old x 100. Thus, the stock increased by: (32.1 - 30)/30 = 2.1/30 = 21/300 x 100 = 21/3 = 7 percent Answer: D _________________ # Scott Woodbury-Stewart Founder and CEO Scott@TargetTestPrep.com 122 Reviews 5-star rated online GMAT quant self study course See why Target Test Prep is the top rated GMAT quant course on GMAT Club.
