Ever person ege, will increase every year, soo given question says that three years ago then age is decreased,

Let the present ages of Amar, Akbar, and Anthony be x,y,z.

Given, total ages of Amar, Akbar and Anthony is 80 years i.e x+y+z=80,

So the total of their ages three years ago will be,
x-3+y-3+z-3=80,
=> x+y+z-9=80,
=> x+y+z=80-9,
=71.

@All.

Decrease 1 year by 1year so then 3 years they decreased their age by 3 years by 3 persons
Then 80-3 * 3 = 71.

Total 3 Members, age is 80.
That is 80/3 = 26.2.
26,26,28 = 80.
3 years ago,
23, ,23, 25 = 71.
Hence Proved "71".

Total age 80.

Simply subtract 3 from all the three =9.
=> 80-9=71.
