Question
There are five consecutive natural numbers. Find the
highest number. Statement I: The average of given five consecutive numbers given is 74. The least number is 72. Statement II: Second highest number is a multiple of 5. The question consists of four statements numbered “I, II, III, IV” given below it. You have to decide that data provided in which of the following statement alone is sufficient to answer question.Solution
The average of five consecutive numbers is 74. Th least number is 72 Therefore, the middle number is 74. Therefore, the highest number = 74-72=2 So, data I is sufficient to answer the question alone.
