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.

The ratio of their present age is 5:4.
After 3 years, the ratio become 11:9.
Now, the difference is not equal which is 6:5 this ratio should be equal whenever to ask such a question. When equal their ratio new ratio is;
10:8
And 11:9.
Then; 1=3.
And asked is 8*3=24.
After 3 years, the ratio become 11:9.

Sameer and Anand age ratio is 5:4.
After 3 years.
Sameer and Anand age ration is 11:9.
The diffrence between presnet and after age is 6 & 5.
After cross multiplying to the difference of ratios samerr age 5x = 5*5 = 25.
Anand age 4x =6*4 = 24.
That's it.

@All.
Here's my solution:.
Here, We need Anand's age.
So first we check the multiple of 4 we get (24, 40) by using elimination.
After 3 years, the new ratio is 11:9 the options become (24+3, 40+3) = (27, 43) the 9 multiple is 27.
So the answer is 27.

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 ?

At last, they have multiplied with 4 that is 4x because they have considered the present age of Anand is 4x we have been asked to find present age of Anand that's why we have multiplied with 4 and we know x=6.
So, 4 * 6 = 24.
So, 4 * 6 = 24.

@Iti and @Sriteja.
Hi friends since they have asked as 3 years ago we have to subtract it and not add.
A+B+C = 80,
Before 3 years or 3 years ago means,
A-3.
B-3.
C-3.
80-9 = 71.
So b4 3 years A+B+C = 71.

2013(present age) = 5 : 4
2016(3 years hence) = 11:9
5x+3/4x+3 = 11/9.
Doing cross multiplication. You'll get value x=6.
We need to sent Anand's present age.
Anand's ratio = 4x.
4*6 = 24.
That the answer.

best tricks for this type of question;
5 :4.
11:9.
4(years Anand age question ask Anand age then multiply)*3(years hence)*2(11-9=2)/(5*9 cross multiply) - (11*4 cross multiply) = 24.
So, the answer = 24.
5 :4.
11:9.
4(years Anand age question ask Anand age then multiply)*3(years hence)*2(11-9=2)/(5*9 cross multiply) - (11*4 cross multiply) = 24.
So, the answer = 24.

Present ages:
Sameer = x.
Anand = y.
x/y = 5/4 -------->eq(1)
After 3 yrs:
x + 3/y + 3 = 11/9 -----------> eq(2)
Solving equations 1 and 2 we get,
9x - 11y = 6,
4x - 5y = 0,
x = 30 and y = 24.
Sameer = x.
Anand = y.

@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.
