KM need not be necessarily integers (Question: 37501.2 )

It is not necessary that distance would be integer. It can be 14.1, 14.2, 14.3 also. Condition for integer is not given. So, not possible to answer this question

Question:
DIRECTIONS: Given question consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. 
How many kilometers did Karan drive today?


I. Karan correctly mentions that he drove less than 20 km but more than 14 km today.


II. Karan’s friend correctly mentions that Karan drove more than 10 km but less than 16 km today.

Options:
A) The data in Statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question.
B) The data in Statement II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question.
C) The data either in Statement I alone or in Statement II alone are sufficient to answer the question.
D) The data in both the Statements I and II are not sufficient to answer the question.
E) The data in both the Statements I and II together are necessary to answer the question.
Solution:

From statement I,

Karan correctly mentions that he drove less than 20 km but more than 14 km today. So, it can be 15,16,17,18 or 19 km. So statement I alone is not sufficient to answer the question.

From statement II,

Karan’s friend correctly mentions that Karan drove more than 10 km but less than 16 km today. So it may be 11, 12,13,14 or 15 km. So statement II alone also is not sufficient to answer the question.

Now, on combining both the statements,we get Karan drove 15 km.

Hence, the data in both the Statements I and II together are necessary to answer the question.
