3. ThiS is an ancient problem dating back to about 310 A.D. Demochares had lived one-fourth of his life as a boy, one-fifth as a youth. one-third as a man, and has spent thirteen years in his dotage- How old is Demo-chares?
Ans: Let Demochares lived in x years
As a boy had lived = x/4
As a youth had lived = x/5
As a man had lived = x/3
spent thirteen years in his dotage
x/4+x/5+x/3+13 = x
x = 130 Years
