Let the present ages be x:x:x.
Therefore total ages = 80,
3x = 80,
x = 80/3.
Before 3 yrs their ages be x-3:x-3:x-3.
Total = 3x-9,
= 3(80/3)-9,
= 80-9,
= 71.
Therefore total ages = 80,
3x = 80,
x = 80/3.
Before 3 yrs their ages be x-3:x-3:x-3.
Total = 3x-9,
= 3(80/3)-9,
= 80-9,
= 71.

Every year each ones age will increase by 1 therefore together it would be 1+1+1 = 3, (Amar + Akbar + Anthony's total age grew by= 3 years in one year).
Now what would be the total increment in their age in 3 years, i.e., 3x3=9.
9 years is how. Much all the 3 of them together grew, so minus 9 from 80 which is their present total age.
= 71.

Amar+anthony+akbar=80.
We divide 80 into 3 parts as 26.5.
He said 3 yrs means cut in 26.5-3 then 23.5.
Then we add 23.5+23.5+23.5 = 70.5 exactly 71.

= 80 - (amar3+akbar3+anthony3).
= 80 - (9 their ages).
= 71.
= 80 - (9 their ages).
= 71.

A simple logic behind the problem is;
80 - 3 * 3.
=> 80 - 9 = 71.
80 - 3 * 3.
=> 80 - 9 = 71.

How? The questions is total 3 persons age is 80 years then 3 years back if we calculate it will be 77. Then how 71 is possible?
