On which day, Roma went to Chennai, if week starts on Monday?
(A) Roma took leave on Wednesday.
(B) Roma went to Chennai the next day of the day his mother came to his house.
(C) Roma’s mother came to his house neither on Monday nor Friday.
Choose the most appropriate answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Even (A), (B) and (C) together are not sufficient
In data sufficiency, the statements are enough only if they fix one single answer. Here the day Roma went to Chennai depends on the day his mother came, since he went on the next day.
(A) only says Roma took leave on Wednesday; it does not say he went to Chennai that day.
(B) ties Roma’s trip to the day after his mother’s visit, but does not give that day.
(C) rules out Monday and Friday for the mother’s visit, which still leaves Tuesday, Wednesday, Thursday, Saturday and Sunday.
Together, Roma could have gone on Wednesday, Thursday, Friday, Sunday or Monday; the leave on Wednesday does not force any one of these.
