Positive integer y is 50 percent of 50 percent of positive integer x, and y percent of x equals 100. what is the value of x ? Select the correct option
A) 50 B) 100 C) 200 D) 1000 E) 2000
Given:   x &gt;0 and y &gt; 0   y = 5010050100(5010050100*x) = 0.25x - (i)   y100y100*x = 100. Hence xy = 10000 - (ii)   Required: Value of x   Substituting the value of y in (ii)   x*0.25x = 10000   x2x2 = 100*100*100/25 = 4*100*100   x = 200 and - 200   We will consider only the positive value as we are told that x &gt; 0   x = 200   Option 200
