PROBLEM #3 :
A man lived one-fourth of his life as a boy in Baltimore, one-fifth of his life as a young man in Youngstown, one-third of his life as a man in Manitoba, and the last thirteen years of his life in Thurmont. How old was the man when he died? Write down your answer.

X = X/4 + X/5 + X/3 + 13
60X = 15X + 12X + 20X + 78060X = 47X + 78013X = 780
X = 60 yearsIOT
