Question
B is 4 years older than A and A is 7 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.Solution
Let C’s present age be x years. So, A’s present age = (x + 7) years And B’s present age = (x + 7 + 4) = (x + 11) years According to question, => x + 7 + x = 25 => 2x = 18 => x = 9 Required total sum = x + (x + 7) + (x + 11) = 3x + 18 = 45 years
