  I. 5 years ago, Arun's age = 2 x His son's age.
III. 5 years hence,
Arun's Age
=
12
Son's age
7
Clearly, any two of the above will give Arun's present age.
 Correct answer is (D).
              99.    
Answer: A
Explanation:
  I. Let Ravi's present age be x years. Then, his father's present age = 2x years.
 II. After 5 years,
Ravi's age
=
6
Father's age
11
III. Ravi is younger than his brother.
From I and II, we get
x + 5
=
6
.   This gives x, the answer.
2x + 5
11
Thus, I and II together give the answer. Clearly, III is redundant.
 Correct answer is (A).
              100.
