Hi, You might want to try the method of elimination for this question as well. Here, y is 50% of 50% of x. Simply put, y = 1/2 * 1/2 * x = 1/4x; Thus, y = 1/4x Also, x% of y = 100 Now, start looking at the options for the question: A. 50 B. 100 C. 200 D. 1000 E. 2000 While, it is a good practice to ...
