Trick type 1 (comparing earlier and present ) Son's age = t1 (x-1) / x-y (comparing later and present ) Son's age = t2 (z-1) / y-z (comparing earlier and after ) Son's age = t1 (x-1) + t2 (z-1)/ x-z where t1 - t years earlier t2 - t years hence Father's age to that of son = x times (earlier/before) Father's age to that of son = y times ( present) Father's age to that of son = z times (after/hence ) PROBLEM 1 The age of a man is four times that of his...
