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? Who cares I don't wanna do this math



Answer :

your answer is 90 because 2,3,5 are factors of 90 but 4 is not a factor of 90.
