Cherry is three times as old as one of her students, May. Four years ago, she was four times as old as May was at that time. How old is May?

Sagot :

Let Cherry's age now be C and May's present age be M
[tex]C-4=4(M-4) \\ C-4=4M-16 \\ C=4M-12[/tex] and [tex]C=3M[/tex]
So that means:
[tex]4M-12=3M \\ M=12[/tex]

Therefore May is 12 years old and Cherry is 36.
