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?
24
27
40
Cannot be determined
None of these
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.

@vinothini good method.

I hope my solution will help you...

Now Sameer age be x, Anand be y.

Ratio is x/y = 5/4 fine.... then 3 years after right, so x+3/y+3 = 11/9,

Then, will produce the eqn...4x=5y--------->1

9x+27=11y+33---------->2

We obtain that is x=5y/4, put into eqn 2,

9*5y/4-11y=33-27
45y-44y=6*4

y = 24 so simple friends.

Given Ratio 5:4----->(1)
Difference between the ratio is 1
After three years 11:9---->(2)
Difference between the ratio is 2
Both the ratio difference are not same.

So muliply (1) by 2, we get 10:8
||ly multiply (2) by 1, we get 11:9. now the difference are same
Anand's present age=8*3=24 years

Can any one tell me how to read 4x and 5x. In both value we can assign same variable? Is it possible?

Rk333 said:   1 decade ago
Here Sameer age & Anand age are assigned to x.

How is it possible? why we can't take two variables?

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

Shyam kumar said:   1 decade ago
Could any explain why should we multiply 4x.

Three year hence means AFTER THREE YEAR.

So, WE ADD 3 YEAR OK GUYS.
