Present ages of Kiran and Shyam are in the ratio of 5 : 4 respectively. Three years hence, the ratio of their ages will become 11 : 9 respectively. What is Shyam's present age in years? | [

] | D | Ratio of the present age of Kiran and Syam = 5 : 4
=Let the present age of Kiran = 5x
Present age of Shyam = 4x
After 3 years, ratio of their ages = 11:9
= (5x + 3) : (4x + 3) = 11 : 9
= (5x+3) / (4x+3) = 11/9
= 9(5x + 3) = 11(4x + 3)
= 45x + 27 = 44x + 33
= x = 33-27 =6
Shyam's present age = 4x = 4×6 = 24
