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.
Is Ravi heavier than Rohit?
I. Rohit is not lighter than Ranjan.
II. Ratan is of the same weight as Ravi. Rohit is heavier than Ratan.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Statement II alone is sufficient, but statement I alone is not sufficient.
In data sufficiency, a statement is sufficient if it gives a definite answer, yes or no; a definite “no” also answers the question. Each statement is tested on its own.
Statement I alone (Rohit is not lighter than Ranjan):
It compares Rohit with Ranjan only and says nothing about Ravi: not sufficient
Statement II alone (Ratan = Ravi, Rohit heavier than Ratan):
Rohit is heavier than Ratan, and Ratan weighs the same as Ravi
So Rohit is heavier than Ravi, and the answer is a definite “no”: sufficient
