arithmetic - six years ago the ratio of the ages of kamal and suprajith was 6 5 four years hence the ratio of their ages will be 11 10 what is suprajiths age at present - skillgun

Let the ages of Kamal and Suprajith 6 years ago be 6x and 5x years respectively.
Then, ((6x + 6) + 4)/((5x + 6) + 4 ) = 11/10
10(6x + 10) = 11(5x + 10)
5x = 10
x = 2.
Suprajith's present age = (5x + 6) = 16 years.
