Q. In the set of {300, 301, 302, ...., 498, 499, 500}, How many numbers will be divisible by 3?
Answer: 67
Notes: The very first number in this series {300, 301, 302, ...., 498, 499, 500} is 300 and last number is 498, so now we have to calculate the total numbers from 300 to 498, are divisible by 3 (498-300/3) + 1 = 67, here we added 1 because 498 and 300 both are divisible by 3. So the right answer is option (c)
