Aptitude - Problems on Ages - Discussion

Hai @Iti the problem can be solved as,

a+b+c=80 then after 3 years (a+3)+(b+3)+(c+3)=80+9=89

The given problem can be solved in other method as,

Given x/y=5/4;
After 3 years (x+3)/(y+3)=11/9;
Solving 9x-11y-6=0;
4x-5y=0;

We get x=30 y=24 Hence answer is 24 years.

Can any one tell me that how 4x has occured.

Could any explain why should we multiply 4x.

Three year hence means AFTER THREE YEAR.

So, WE ADD 3 YEAR OK GUYS.

Three years hence ======> three years from present age.

The dictionary meaning for the word "hence" is "FROM NOW".

I think this will be useful in calculations.

Ratio of the age of two persons is given. Let their age be in the ratio 5x &4x. it becomes 5x/4x .then in the question it is given,3years hence{means after 3years} then add 3in 5x/4x then we get 5x+3/4x+3.but in the question it is given that after 3years the ratio becomes 11\9 .SO IT becomes as 5x+3/4x+3=11/9. Now we can solve the question...

Give solution for 11/9.

In the answer column they put 24 as the answer, please answer to my doubt if anand current age is 24 (as specified) then 3 years later his age will be 21 then how will you specify the age 21 in 5:4. Can divide the age 21 by 4 ?

Three years hence, the ratio of their ages will become 11 : 9 respectively.

So we need to add 3 on both side.

I think here is an error in answer,

If anand present age is 24(as 4 * 6 = 24, sameer age would be 5 * 6 = 30), here as mentioned in the question the ratio of their present age should be 11/9, but here the ratio according to the ans would be 30/24=5/4(5:4)(as per present age).

But we need to get 11/9 as the ration.

Anands present age would be 4x + 3 = 4*6+3=24+3 = 27.
And Sameer present age would be 5x + 3 = 5*6+3 = 33.
Then the ratio will satisfy, as 33/27 = 11/9(11:9 present ratio).

Can anyone justify existing answer.
