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.

Thank you its great to see like this problems make mind really sharp, off course however there is 3 persons so we took out from every one 3 years so like that if we do means it must be 9, which has to be taken out from total age.
So 80-3-3-3=71.
Thanks I got it and I tried to explain to stranger who won't get it.

Actually the confusion some are facing is the value provided is not average so there is no need for multiplying 8083 - 9 again divide by 3.
The answer is simple they given 80 in total and asked for deducting 9 from 80 as 3 people * 3 years each = 9.
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.

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.

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.

Yes, this is right why because the total age of three persons is 80,before three years, we have to subtract each three with the total age. i.e,(80-3+3+3) = 71.
That's all.
That's all.

Suppose Amar is 25, Akbar 35 and Anthony 20 years old, total comes to 25+35+20 = 80.
Now 3 years before their age would be 25-3, 35-3 and 20-3 i.e. 22+32+17 = 71 years.
Now 3 years before their age would be 25-3, 35-3 and 20-3 i.e. 22+32+17 = 71 years.

Let the 3 persons age be 50, 28 and 2 (50+28+2 = 80).
Before 3 years, age be 47, 25, 0.
So, total age before 3 years(47 + 25 + 0 = 72).
Note: Age can not be negative.
Before 3 years, age be 47, 25, 0.
So, total age before 3 years(47 + 25 + 0 = 72).
Note: Age can not be negative.

Please note the question they asked total of their age is 80 years 3 years before.
So here total persons are 3 and 3 years before (so 3x3 = 9, then 80-9 = 71 years.
So here total persons are 3 and 3 years before (so 3x3 = 9, then 80-9 = 71 years.
