GIVEN: 75 percent of x equals 125 percent of y
Rewrite as: 3/4 of x = 5/4 of y
Or we can say: (3/4)(x) = (5/4)( y)
Multiply both sides by 4 to get: 3x = 5y
Divide both sides by 5 to get: 3x/5 = y
Rewrite as: y = (3/5)(x)
Or y = 3/5 of x
Or y = 60/100 of x
Or y = 60% of x

Answer: C

\(X = 100\), then (75% of \(X\)) \(= 75\)

\(75 = 125\)% of \(Y\)
\(75 = 1.25Y = \frac{5}{4}Y\)
\(\frac{4}{5}\cdot 75 = Y\)
\(\frac{300}{5} = Y \)
\(60 = Y \)

Thus, \(Y = 60\) when \(X = 100 \), or equivalently, \(y=60\)% of \(X\)

We can create the equation:

0.75x = 1.25y

75x = 125y

(75/125)x = y

(3/5)x = y

We see that y is 3/5, or 60%, of x.
