Sum of the present ages of A, B and C is 110 years. 22 years ago from the present the ratio of ages of A, B and C was 4 : 5 : 2. What is the sum of present ages of A and C?
Show answer & explanation
Correct answer: C
Explanation
Let's assume (22 years ago):
A = 4x
B = 5x
C = 2x
Current Age:
A = 4x + 22
B = 5x + 22
C = 2x + 22
Total Age:
(4x+22)+(5x+22)+(2x+22)=110
11x+66=110
11x=44
x=4
Now A + C:
A+C=(4x+22)+(2x+22)
=6x+44
=6(4)+44
=24+44
=68
Final Answer = (C) 68 years
