The question below is followed by two statements numbered I and II. Decide whether the data given in the statements are sufficient to answer the question.
At what time did the train leave today?
I. The train normally leaves on time.
II. The scheduled departure time is 14:30.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Neither statement I nor statement II is sufficient.
In data sufficiency, a statement is sufficient only if it leads to one definite answer; each statement is first tried alone, then the two together.
Statement I alone:
It gives no time at all: not sufficient
Statement II alone:
It gives the scheduled time, not the time the train actually left today: not sufficient
Both together:
The train normally leaves at 14:30, but “normally” does not mean always; it may have been late today, so the time is still not definite
