I always empty the coins from my pockets in a bowl when I get home. The size of the bowl is approximately 2-1/2 cups. When the bowl gets full , I cash it out at a Coin-star machine.

Q1 Brain Teaser) What percentage of the coins are quarters, dimes, nickles and pennies?

Q2 Tie Break ?) Approximately how much dollar values is in the bowl?



*assume no half or whole dollar coins
**Factual answer to follow

Well I guess that would be true.... but I mean what % of each coin comprise the total of the 100%.

It's not a trick question!!

It might not be a trick question but it isn't a clear question.

% of the weight or volume?
% of the number of individual coins?
% of the value of the coins?
