Question:

On which day of the week was birthday of Arjun if week is starting from Monday?

(I) Arjun celebrated his birthday the very next day on which Sahil celebrated his birthday.
(II) The sister of Arjun was born on the fifth day of the week and two days after Arjun was born.

Options:

if the data in statement I alone are sufficient to answer the question

if the data in statement II alone are sufficient to answer the question

if the data either in statement I alone or in statement II alone are sufficient to answer the question

if the data in both statement I and II together are necessary to answer the question

Correct Answer:

if the data in statement II alone are sufficient to answer the question

Explanation:

SI: Arjun celebrated his birthday the very next day on which Sahil celebrated his birthday. Sahil has nothing to take with Arjun's Birthday as Sahil has not been mentioned in any other statement. Thus, Statement I is irrelevant.

SII: The sister of Arjun was born on the fifth day of the week and two days after Arjun was born. 5th day of week is Thursday and if Arjun was born 2 days before his sister thus to conclude Arjun was born on Tuesday.

The correct answer is Option (2) → if the data in statement II alone are sufficient to answer the question
