Math Challenge 14

Sometimes when you go for shopping, you may encounter items on offer.

10% discount, 36% discount, ......

So if a $18 toy is put up at a discount of 25%, and another toy, priced at $25, is at a discount of 18%, which has a bigger reduction in dollars?

Do not use calculator, though, to answer this challenge.
Otherwise all the toys will be gone!

Be quick.....

Answer please.

Obviously, none.
In both cases we multiply by the same numbers, hence the reduction is the same, 4.5 dollars.

by calculation in both cases we have value of 4.5 so no one is bigger both are same.
