Question
B is 3 years older than A and A is 6 years older than C.
If the sum of the age of A and C is 26 years, then find the sum of the ages of all three.Solution
Let C’s present age be x years. So, A’s present age = (x + 6) years And B’s present age = (x + 6 + 3) = (x + 9) years According to question, => x + 6 + x = 26 => 2x = 20 => x = 10 Required total sum = x + (x + 6) + (x + 9) = 3x + 15 = 45 years
