Answer:
Let Ravi's present age be x years. Then, his father's present age = 2x years.
II. After 5 years,
Father’s age
Ravi’s age
=
11
6
III. Ravi is younger than his brother.
From I and II, we get
2x+5
x+5
=
11
6
. This gives x, the answer.
Thus, I and II together give the answer. Clearly, III is redundant.
