The age of four friends A, B, C and D is (x + 2), (x – 4), x, and (x + 5) years, respectively. Then, find the ratio between the present age of C and D?
I. The average age of B and C after 4 years will be (x – 18.5) years less than the average age of A and D after 10 years.
II. The average age of A and C after 5 years is 1 year more than the average age of B and C after 7 years.1
The data in both the statements I and II together are necessary to answer the question.
2
The data either in statement I alone or in statement II alone are sufficient to answer the question.
3
The data in both the statements I and II together are not sufficient to answer the question.
4
The data in statement II alone are sufficient to answer the question, while the data in statement I above are not sufficient to answer the question.
5
The data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
