Terry has between 50 and 100 pennies and her piggy bank. She can count them two at a time and come out even. She can also count them three and five at a time and come out even. She cannot count them 4 at a time and come out even. How many pennies does she have?
The # is multiple of 2,3 and 5, but not 4. The smallest number possible in here is 105. This means that some of this is in the bank?
