Answer 1

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.

∴ Correct answer is (A)
