Present ages of Sameer and Anand are in the ratio of 5 : 4 respectively. Three years hence, the ratio of their ages will become 11 : 9 respectively. What is Anand's present age in years?
Answer: Option
Explanation:
Let the present ages of Sameer and Anand be 5x years and 4x years respectively.
| Then, | 5x + 3 | = | 11 |
| 4x + 3 | 9 |
9(5x + 3) = 11(4x + 3)
45x + 27 = 44x + 33
45x - 44x = 33 - 27
x = 6.
Anand's present age = 4x = 24 years.

Why the number 3 is added to 5x and 4x?

Anand present age:
4*(11-9)*3/5*9-11*4 = 4*2*3/1 = 24.
4*(11-9)*3/5*9-11*4 = 4*2*3/1 = 24.

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.

@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.

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

3(11-9)/5*9-11*4 = 6.
Sameer and Anand present ratio is 5:4.
6*4 = 24.
Sameer and Anand present ratio is 5:4.
6*4 = 24.

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

Hi, please explain the second step of the solution.
In this part of the equation 45x + 27 = 44x + 33. How +27 and + 33 came?
