The following question has two statements. Study the question and the statements carefully and then decide which of the statement(s) is/are necessary to answer the question. Ashutosh, Kamal And Bhawna undertook a work for Rs. 5000. Find Ashutosh’s share.  I∶ Ashutosh and Bhawna can finish the work together in 10 days  II∶ All three together can finish the work in 6 days while Kamal alone takes 15 days to complete the work. Correct Answer Statement I and statement II together are not sufficient to answer the question.

Statement I∶

Statement I alone does not signify anything

Statement II∶

Let total units of work = 30 units (LCM of 6 & 15)

∴ Efficiency of Kamal = 30/15 = 2

Overall Efficiency = 30/6 = 5;

∴ Sum of efficiencies of Ashutosh and Bhawna = 5 – 2 = 3

We can’t find the efficiency of Ashutosh with the help of statement II also.

∴ Statement I and statement II together are not sufficient to answer the question.
