From statement I: Lucy is half of the age of her mother who was 43 years old 5 years back. So, now Lucy’s mother’s age is 48 years. Hence, Lucy’s age will be 24 years. But, our question cannot be answered as age of Kate is not known. ∴ Statement I alone is not sufficient to answer the question. From statement II: Kate is younger sister of Lucy and is one third the current age of her mother. With this, ages of Kate and Lucy cannot be found, and hence question cannot be answered. ∴ Statement II alone is not sufficient to answer the question. From statements I and II together: Lucy is half of the age of her mother who was 43 years old 5 years back. So, now Lucy’s mother’s age is 48 years. Hence, Lucy’s age will be 24 years. Kate is younger sister of Lucy and is one third the current age of her mother. So, Kate’s age = 48/3 = 16 years Now, the question can be answered as ages of Kate and Lucy are known. ∴ Using both the statements together, we can answer the given question.Related questions
