E 200x/(y + 3)

Rewrite: twice the value of x is what percent of three more than y?

Twice the value of x \(= 2x\)
Three more than y = \(y + 3\)

\(\frac{part}{whole} * 100 =\) percent

\(\frac{2x}{(y + 3)} * 100 =\) percent

percent = \(\frac{200x}{(y + 3)}\)

Answer E

The answer should be E as follows.

Let the percentage we have to find out is z.

As per the condition given,

\((\frac{z}{100})*(y+3)=2x\) ==> \(z=\frac{2x*100}{(y+3)}\) ==>\(\frac{200x}{(y+3)}\)

Hence answer is E

We can translate “what percent of three more than y is twice the value of x” into an expression in which n is the percent:

(n/100)(y + 3) = 2x

n/100 = (2x)/(y + 3)

n = (200x)/(y + 3)

Answer: E
