Total of Ages
The total of the ages of Amar, Akbar, and Anthony is 80 years. Let's denote their ages as follows:
- Amar's age: A years
- Akbar's age: B years
- Anthony's age: C years
Given that the total of their ages is 80 years, we can write the equation:
A + B + C = 80
Finding the Total Three Years Ago
To find the total of their ages three years ago, we need to subtract 3 from each of their ages. Therefore, the equation becomes:
(A - 3) + (B - 3) + (C - 3) = ?
Simplifying the Equation
Let's simplify the equation:
A - 3 + B - 3 + C - 3 = ?
(A + B + C) - 9 = ?
80 - 9 = ?
Calculating the Answer
Now, we can calculate the answer:
80 - 9 = 71
Answer: The total of their ages three years ago was 71 years.
Explanation
The answer is option A (71 years) because when we subtract 3 from each of their ages and add them up, we get a total of 71 years. This means that three years ago, their total age was 71 years.
