Aptitude - Problems on Ages - Discussion

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.

Why we take x for both?. May we take 2 different variables. I m not getting really.

3(11-9)/5*9-11*4 = 6.

Sameer and Anand present ratio is 5:4.

6*4 = 24.

Given ratios :

5:4 and 11:9 now.
3x2 (difference of 11:9)/45-44(5*9-4*11).
= 6x4 = 24 .

@Vijay.

I think there is mistake in your solution.

According to me a = 50 and b = 20.

As the first equation can also be written as a-5 = 3(b-5).

To make it present 5 is subtracted both sides.

I think 27 is answer. Because, When you take present ratio as 11:9, Sameer age will be 33 and Anand age will be 27 (multiplied by 3). When you go back 3 years.

Their age will be 30 and 24 (divided by 6). So, it will be of ratio 5:4. which is correct ratio as given data. Explain if I am wrong.

All explanations are good but some errors are present.

Please help me, I still don't understand. How we got 11/9?

Anand present age:

4*(11-9)*3/5*9-11*4 = 4*2*3/1 = 24.

Dear all nice answer thank you.
