Question

If present age of Ravi father is x what will be his father age after 9 years

Answer 1

Let Ravi's present age be x years. Then, his father's present age = 2x years.

• II. After 5 years, Father’s ageRavi’s age=116
• III. Ravi is younger than his brother.
• From I and II, we get 2x+5x+5=116. This gives x, the answer.

Thus, I and II together give the answer. Clearly, III is redundant.
