If x and y are positive integers, what percent of three more than y is twice the value of x?
A \(\frac{1}{200x(y + 3)}\)
B \(\frac{y + 3}{200x}\)
C \(\frac{100(y + 3)}{2x}\)
D \(\frac{200x}{y} + 3\)
E \(\frac{200x}{y + 3}\)
A \(\frac{1}{200x(y + 3)}\)
B \(\frac{y + 3}{200x}\)
C \(\frac{100(y + 3)}{2x}\)
D \(\frac{200x}{y} + 3\)

E should be the answer. .
The reqd percentage , say = p
p ( y+3) / 100 = 2*x
p = 200*x / y + 3
The reqd percentage , say = p
p ( y+3) / 100 = 2*x
p = 200*x / y + 3

Let unknow percent be T%
T% * (3+y)=2x
T%=2x/(y+3)
T=2x*100/(3+y)
T=200x/(3+y)
Option E.
T% * (3+y)=2x
T%=2x/(y+3)
T=2x*100/(3+y)
T=200x/(3+y)
Option E.
