The average age of A and B, 2 years ago was 26. If the age of A, 5 years hence is 40 yrs, and B is 5 years younger to C, then find the difference between the age of A and C?
Solution
Correct Answer: Option B
Let the present ages of A and B be 'x' and 'y' respectively
From the given data,
[(x-2) + (y-2)]/2 = 26
=> x+y = 56
But given the age of A, 5 years hence is 40 yrs => present age of A = 40 - 5 = 35 yrs
=> x = 35 => y = 56 - 35 = 21
=> Age of B = 21 yrs
Given B is 5 years younger to C,
=> Age of C = 21 + 5 = 26 yrs
=> Required Difference between ages of A and C = 35 - 26 = 9 yrs.
