Correct Answer: If the Statement II alone is sufficient to answer the question but the Statement I alone is not sufficient
Explanation:
From Statement I,
Raveena is half as old as Karishma. But we don't know the age of Karishma.
From Statement II,
Age of Raveena = three-fifth of her mother's age
Age of Raveena = Age of her Mother x 3/5
Age of Raveena = 45 x 3/5 = 27 yr
