The question below is followed by two statements numbered I and II. Choose the option that describes whether the statements are sufficient to answer the question.
How old is Nisha today?
I. Four years from now, Nisha will be 21 years old.
II. Nisha is exactly one-third as old as her aunt Meenu, who is 51 years old today.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → The question can be answered by using either statement alone.
In data sufficiency, a statement is sufficient only if it leads to one definite answer; each statement is first tried alone.
Statement I alone:
Nisha’s age today \(=21-4=\) 17 years: sufficient
Statement II alone:
Nisha’s age today \(=51\div3=\) 17 years: sufficient
