Question

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 1

Let the present age of sameer and anand be 5x and 4x respectively.
Then,
(5x + 3)/(4x + 3) = 11/9
9(5x + 3) = 11(4x + 3)
45x + 27 = 44x + 33
45x - 44x = 33 - 27
x = 6.
The present age of Anand =4x=24.

Answer 2

Let the present ages of Sameer and Anand be 5x years and 4x years respectively.

Then,5x + 3/4x + 3 = 11/9

9(5x + 3) = 11(4x + 3)

45x + 27 = 44x + 33

45x - 44x = 33 - 27

x = 6.

Anand's present age = 4x = 24 years.
