Ollie forgot his money. Mandy gave Ollie one-fifth of his money, Luke gave Ollie one-fourth of his money and Nicholas gave Ollie one-third of his money. How much of the group’s money does Ollie have now?
Answered by oobleck
no way to tell, unless each of the three had the same amount. In that case,

1/3 (1/5 + 1/4 + 1/3) = 47/180

Pardon me Mr. oobleck, the amounts were the same.
