Question

Which of these is the odd one out?
A. 2012
B. 2010
C. 2008
D. 2004

Answer 1

Hint: 2012, 2010, 2008, 2004 are the even numbers. Based on the given numbers it is divisible by 2 and we need to check if it is divisible by 4. As keeping mathematics away from these, we can find the odd one out by checking the leap year numbers.

Complete step-by-step answer:
We need to find the odd one out from the given options A. 2012 B. 2010 C. 2008 D. 2004
Out of 2012, 2010, 2008, 2004 let’s check one by number.
2012 is divisible by 4, 2012 is a leap year.
2010 is not divisible by 4, and it is not a leap year.
2008 is divisible by 4, and it is a leap year.
2004 is divisible by 4, 2004 is a leap year.
Leap year is a calendar year that contains an additional day added to keep the calendar year synchronized with the astronomical year or seasonal year. The extra day is added to the month of February. So we will have 366 days in a leap year.
Therefore, 2010 is odd one out since rest all are divisible by 4 but 2010 is not divisible by 4.
Also it is not a leap year.
