Three-fourth of a number is equal to 60% of another number. What is the difference between the numbers?

Let the numbers be x and y respectively. Then,

$frac{3}{4}x = 60{ m{\% ;of;}}y$

$Rightarrow frac{3}{4}x = frac{{60}}{{100}}y$

$Rightarrow frac{3}{4}x = frac{3}{5}y$

$Rightarrow y = frac{3}{4} imes frac{5}{3}x = frac{5}{4}x$

$herefore y - x$

$= frac{5}{4}x - x = frac{x}{4}$

Clearly, no unique answer is possible.
