Which of the following is true about average?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. The average of six consecutive odd integers is an even integer.
Let the six concecutive odd integers be 1, 3, 5, 7, 9 and 11.
Average = (1 + 3 + 5 + 7 + 9 + 11)/6
⇒ 36/6 = 6 (Even integer)
Hence option 1 is correct.
Let the six consecutive even numbers be 2, 4, 6, 8, 10 and 12.
Average = (2 + 4 + 6 + 8 + 10 + 12)/6
⇒ 42/6 = 7 (Odd integer)
