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

Let 80- three years ago* three persons

80-3 * 3 = 80 - 9 = 71.

Let 80- three years ago* three persons

80-3 * 3 = 80 - 9 = 71.

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.

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.
