arithmetic - present ages of kranthi and sundaram are in the ratio of 5 4 respectively three years hence the ratio of their ages will become 11 9 respectively what is sundarams present age in years - skillgun

Ratio of the present age of Kranthi and Sundaram = 5 : 4
=> Let the present age of Kranthi = 5x
Present age of Sundaram = 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
Sundaram's present age = 4x = 4×6 = 24
