4 minutes 12 seconds is 252 seconds
3 minutes 54 seconds is 234 seconds

252 seconds for 462 beats is in proportion with 234 seconds with some number of beats [tex]x[/tex]

Set up the proportion:
[tex]\frac{252}{462}=\frac{234}{x}[/tex]
⇒[tex]252x=234*462[/tex]
⇒[tex]252x=108108[/tex]
⇒[tex]x=429[/tex]

So the new song has 429 beats.
