Using pennies, nickels, dimes or quarters, determine which kind of coin is in each circle in the answer Colum. First clue: The total value of the four coins is an odd number.

Question

Second clue: The sum of the value of the middle 2 coins is 11 cents.
Third clue: Each coin is worth the same as or more than the coin to its left (coin C is worth the same as or more than the coin B).
The order for the circles is circle A, B, C, D. Please explain how you got your answer.

Answer 1

a <= b <= c <= d
b+c = 11
so, since b<=c, b=1 c=10
so, b+c is odd, a+d is even, and
since b=1, a=1 since a <= b
if a+d is even, is odd and the coins are

1 1 10 25

since 10 <= d
