    Largest sum

    What's the largest sum of money --- all in coins and no silver dollars ---
    that you could have in your pocket without being able to give change
    for a dollar, a half-dollar, a quarter, a dime, or a nickel?
    Answer: $1.19


    Uh, how exactly? How would you get $1.19 . . . you would have to have pennies in there (which means you wouldn't be able to make change for the other coins, but then the largest could be $39293392.03 [or higher]) . Anyone?

    Cannot change a nickel......so maximum of 4 pennies.
    Cannot change a dime........so no need for a nickel.
    Cannot change a quarter....so need to have at least 2 dimes.
    Cannot change a half-dollar......so need a quarter and another 2 dimes.
    Cannot change a dollar.....so need a half dollar.

    4 pennies = $0.04
    4 dimes = $0.40
    1 quarter = $0.25
    1 half-dollar = $0.50
    ----------------------
    Total = $1.19

    Note;
    4@1c +2@5c +1@10c +1@25c +1@50C = $0.99 will not change a nickel, a dime, a quarter, a half-dollar nor a dollar too. But it is only $0.99

    4@1c +3@10c +1@25c +1@50c = $1.09 will not change a nickel, a dime, a quarter, a half-dollar, nor a dollar also. But it is only $1.09.

    $1.19 is more than $0.99 or $1.09.
