Question

B is 4 years older than A and A is 6 years older than C. If the sum of the age of A and C is 22 years, then find the sum of the ages of all three. 

A 40 years Correct Answer Incorrect Answer
B 43 years Correct Answer Incorrect Answer
C 37 years Correct Answer Incorrect Answer
D 45 years Correct Answer Incorrect Answer

Solution

Let C’s present age be x years.  So, A’s present age = (x + 6) years  And B’s present age = (x + 6 + 4) = (x + 10) years  According to question, => x + 6 + x = 22  => 2x = 16 => x = 8 Required total sum = x + (x + 6) + (x + 10) = 3x + 16 = 40 years
