Brain teaser: I have two Indian coins that have a total value of 75 paise, but one of the coins is NOT a 50 paise coin. So what two coins do I have? The valid coins (I believe) are: 10 paise, 20 paise, 25 paise, 50 paise

OpenStudy (mr.math):

50 and 25.

OpenStudy (mr.math):

The one that's NOT 50 is the 25 one.

OpenStudy (asnaseer):
