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.

Sri said: (Jun 11, 2011)  
Please give me explanation clearly.

Bkm said: (Nov 8, 2011)  
Your explanation detail clearly.

Amruta said: (Mar 13, 2012)  
See there are 3 person so 3 we've to take then multiple 3 with that 3 person it'll come 9

So 80-3x3=71

Bhaskar Rishi said: (Aug 12, 2012)  
= 80 - (amar3+akbar3+anthony3).

= 80 - (9 their ages).

= 71.

Deep Dey said: (Sep 14, 2012)  
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.

Suresh Manda said: (Jul 2, 2013)  
= 80 - (amar3 + akbar3 + anthony3).

= 80 - 9.

= 71.

Himabindu said: (Jul 7, 2013)  
How could it be 71 it can be 77 because age of Akbar amar and Anthony is 80 after years years means from 80 we have to subtract 3 years. So we get 80-3 = 77.

Sekshavali said: (Sep 1, 2013)  
I really interested this type solving problems please continue this type of problems and solves. Thank you.

Murugavel said: (Nov 12, 2013)  
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.

Rohni Kumar said: (Dec 6, 2013)  
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.

Riya said: (Jan 20, 2014)  
80-(3+3+3) = 80-9 = 71.

TOTAL AGES OF 3 NOS = 80.

THEIR AGES 3 YEARS AGO = 9.

Ghanshyam said: (Apr 29, 2014)  
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.

Abhijit said: (Oct 5, 2014)  
Why 80 subtract by 9?

Naresh Yadala said: (Oct 31, 2014)  
Because in the question has ashing before 3 years age. That's why subtracted.

Elangoraja said: (Nov 4, 2014)  
Avg is 80 so total is 240 only.
Before 3 years total is 231.
So avg will be 231/3.

Upender said: (Nov 29, 2014)  
I don't understand. Can you please explain once again?

Ravinder said: (Dec 27, 2014)  
Simply I understand this problem :

Total 80 before three years their ages.

80-3-3-3 = 71.

Ans is 71.

Atif said: (Jan 26, 2015)  
This model question are very use full in competitive exams thanks to giving good explanation in simple method.

Balz said: (Jan 27, 2015)  
Guys, just note that total of the ages carefully.

William said: (Apr 8, 2015)  
I understand the solution to problem, 80-(3.3) = 71 answer.

Baburao Kola said: (Apr 23, 2015)  
They are 3x3 years ago = 9.
80 - 9 = 71.

Musthafa said: (Jul 10, 2015)  
Good explanation keep it up.

Ravi said: (Oct 6, 2015)  
Thank you friends.

Amrita said: (Dec 3, 2015)  
If their total ages now 80 then three years ago their total ages would be 80-3 = 77.

So, why not 77 is correct?

Prasad said: (Feb 10, 2016)  
In the question mentioned their total age in three years ago. Thank you friends nice question.

Ramlakhanchauhan said: (Apr 14, 2016)  
Yes, 71 it is the right answer.

Lakshmi said: (Apr 14, 2016)  
Thank you friends, for giving a clear and good explanation.

Russ said: (Jul 5, 2016)  
So to get the right answer, all we do subtract 3 from each person to get 71?

Mercynag said: (Oct 10, 2016)  
Thanks for all the discussion.

Alekhya said: (Oct 18, 2016)  
Super explanation @Bhaskar Rishi & @Deep Dey.

Chandu said: (Nov 29, 2016)  
A simple logic behind the problem is;

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

Swetha said: (Nov 30, 2016)  
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?

Goran Roy said: (Dec 29, 2016)  
Thanks for the solution.

Keerthi said: (Jan 10, 2017)  
Thank you all for giving a clear solution.

Mani said: (Feb 2, 2017)  
Simply, 80-3-3-3 = 71 years.

Venkata Rami Naidu said: (Feb 21, 2017)  
71 years is correct.

I also got the same answer.

Omkar Om said: (Mar 5, 2017)  
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.

Prathibha Reddy said: (Mar 8, 2017)  
Let the 3 persons age be 30, 30, 20(30+30+20 = 80)
Before 3 years, age be 27, 27, 17.
So, total age before 3 years(27 + 27 + 17 = 71).

Prasanta said: (Apr 3, 2017)  
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.

Suma said: (Apr 26, 2017)  
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.

Rohan Ramekar said: (May 9, 2017)  
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.

Saiteja said: (Aug 9, 2017)  
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.

Narayana Beja said: (Aug 29, 2017)  
Thanks for the given explanation.

Ramanand said: (Sep 2, 2017)  
Good explanation. Thanks @Suma.

Chandini said: (Sep 16, 2017)  
Their present ages total=80.

3 years ago their total ages= 80- (3*3) =71.

Sunil Gampa said: (Sep 19, 2017)  
Thanks for the good explanation.

Venu said: (Oct 23, 2017)  
Thank you for your nice explanations.

Triloki said: (May 13, 2018)  
77 will be the correct answer.

Rupa said: (May 24, 2018)  
Thanks for all your explanations.

Tauseef Ahmad said: (Jun 30, 2018)  
Total age 80.

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

Gouse Mg said: (Dec 27, 2018)  
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".

Naveen Kumar Teppa said: (Jan 8, 2019)  
@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.

Rachel Praveena said: (Apr 17, 2020)  
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.

Rubyy said: (Sep 13, 2020)  
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.
