Let, Age of Komal = x years
Age of Rohan = (x + 6) years
4 yeas ago;
Age of Komal = (x - 4) years
Age of Rohan = (x + 6 - 4) = (x + 2) years
Now, According to question:
(x + 2) = 4 × (x - 4)
x + 2 = 4x - 16
3x = 18
x = 6
Age of Komal = 6 years
Age of Rohan = 6 + 6 = 12 years
Hence, Age of Rohan is 12 years.
