Question
B is 2 years older than A and A is 5 years older than C.
If the sum of the age of A and C is 25 years, then find the sum of the ages of all three.ÂSolution
Let C’s present age be x years. So, A’s present age = (x + 5) years And B’s present age = (x + 5 + 2) = (x + 7) years According to question, => x + 5 + x = 25 => 2x = 20 => x = 10 Required total sum = x + (x + 5) + (x + 7) = 3x + 12 = 42 years Â
