DIRECTIONS for the question: The question below is followed by two statements marked I and II. Mark as your answer.
What is the unit’s digit of the number where p, q and r are the hundredth, tenth and units digits of the number?
Statement 1: The product of p and q is 12
Statement 2: The product of q and r is 24 and r is greater than 4
A)
If the data in statement (1) alone is sufficient to answer the question
B)
If the data in statement (2) alone is sufficient to answer the question
C)
If the data in both the statements together are needed to answer the question
D)
If either statement (1) alone or statement (2) alone is sufficient to answer the question
E)
If neither statement (1) nor statement (2) suffices to answer the question
B
Statement I: Here no information is given about ‘r’, so the unit digit cannot be found.
Statement II: The product of q and r is 24 and r is greater than 4, so r is 6 or 8. Now in both the cases the unit digit of the number is 6. Hence statement II is sufficient to solve the question.
where p, q and r are the hundredth, tenth and units digits of the number?
