How many oranges can be purchased for 24 dollars at the original price?

(A) 8
(B) 12
(C) 16
(D) 20
(E) 24

Say $$x$$ is the original price of an orange, then:

$$xn=12$$;
and
$$0.6x*(n+4)=12$$ --> $$x(n+4)=20$$ --> $$xn+4x=20$$ --> $$12+4x=20$$ --> $$x=2$$.

So, for 24 dollars 24/2=12 oranges can be purchased at the original price of $2.

So, for 24 dollars 24/2=12 oranges can be purchased at the original price of \$2.

are there any other ways?
