What is the average of all integers between 400 and 550 that are exactly divisible by 17?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 476.
Nearest multiple of 17 to 400 = 408
Nearest multiple of 17 to 550 = 544
Average = (Last multiple + First multiple)/2
⇒ (544 + 408)/2
⇒ 952/2 = 476
