Sum of the present ages of A, B and C is 96 years. 12 years ago from the present the ratio of ages of A, B and C was 1 : 2 : 3. What is the sum of present ages of A and C?
Show answer & explanation
Correct answer: C
Explanation
Total age 12 years ago
12 = 96- 36 = 60
Ages based on the ratio
x + 2x + 3x = 60
6x + 60
x = 10
Individual ages 12 years ago:
A's age (1x)= 1×10=10
C's age (3x)=3×10 = 30
A's current age = = 10+12 = 22
C's current age = 30+12= 42
Sum of A's and C's current ages:
22+42 = 64
