Let Shobo’s age be x years. Therefore, his mother’s age will be 6x years.
According to the given question,
After 5 years.Shobo's age = Shobo's mother's present age/3
x + 5 = 6x/3
x + 5 = 2x
Transposing x to R.H.S, we obtain
5 = 2x - x
5 = x
6x = 6 x 5 = 30
Therefore, the present ages of Shobo and Shobo’s mother will be 5 years and 30 years respectively.
