Question
The question consists of two statements numbered āI
and IIā given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. The ratio of the present ages of 'B' and 'A' is 5:9, respectively. Determine the present age of 'A'. Statement I: 8 years ago from now, 'A' was 24 years older than 'B' Statement II: The ratio of their ages 6 years hence from now will be 3:5, respectively.Solution
ATQ, Let the present ages of B and A be 5a years and 9a years, respectively Statement I: 9a ā 5a = 24 Or, 4a = 24 Or, a = 6 Therefore, present age of A = 9a = 54 years So, data in statement I alone is sufficient to answer the question. Statement II: According to the question, (5a + 6)/(9a + 6) = 3/5 Or, 25a + 30 = 27a + 18 Or, 2a = 12 Or, a = 6 Therefore, present age of A = 9a = 54 years So, data in statement II alone is sufficient to answer the question. So, data either in statement I alone or in statement II alone are sufficient to answer the question.
