Direction: Each of the questions below consists of a question and three statements numbered I, II and III given below it. You have to study the questions and decide the data in which of the statements are sufficient to answer the questions.
-
What is the present age of Subir?

-
- Only I and II
- Only I and III
- Only II and III
- All I, II and III
- Even with all the three statements answer cannot be given.
Correct Option: A
Let, the present age of Subir and his father be S and F, respectively.
| I. S = | F |
| 2 |
| II. After 5 years , | S + 5 | = | 6 | ⇒ 6F - 11S = 25 |
| F + 5 | 11 |
III. Age of Subir’s brother - Age of Subir = 5
⇒ B − S = 5 [ B = age of Subir’s brother]
Now, with the help of I and II together, the value of S and F can be determined.
