The following question has two statements. Study the question and the statements and decide which of the statement(s) is/are necessary to answer the question. A and B started a business and C joined after 6 months. Find the share of C out of total profit at the end of the year. Statement I: Total profit at the end of the year was Rs. 8400. Statement II: C invested Rs. 16500 and his investment was 1.5 times that of A. Correct Answer Statement I and II together are not sufficient to answer the question From statement II: C invested Rs. 16500 for 6 months while A invested Rs. 11000 ( = 16500/1.5) for 12 months, ⇒ Ratio of profits of A and C = (11000 × 12) ∶ (16500 × 6) = 4 ∶ 3 As we do not get any idea about the investment made by B from any of the given statements, we can’t find the required answer. ∴ Statement I and II together are not sufficient to answer the question.
