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.

Sum of their ages 3 years ago = 9 (i.e age of Akbar=3, age of Amar=3 age of Anthony).
Therefore 80 - 9 = 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.
