I need to work this questions.

Six hundred pennies are placed in a row. If every other penny is replaced by a nickel and every third coin us replaced by a quarter, what is the final value of the 600 coins?

Take twelve pennies.

Replace every other penny with a nickel.

Replace every third coin with a quarter.

PPP PPP PPP PPP

PnP nPn PnP nPn

PnQ npQ PnQ nPQ

Now notice how after six, it repeats? So all you have to do is figure the value of the first six, and multiply by 100.

300 nickels, 200 quarters, 100 pennies

very nice solution, I like it!!!

I am sorry but I don't get it.
