Which among the following is not a leap year?

Given : Leap year

Explanation : 

Leap year → To determine if a year is leap year, the year is divisible by (4) i.e. remainder should be zero.

So,

• Option - (1) : 2024 → (2024 ÷ 4) = 0 Remainder ⇒ Leap year
• Option - (2) : 2004 → (2004 ÷ 4) = 0 Remainder ⇒ Leap year
• Option - (3) : 2014 → (2014 ÷ 4) = 2 Remainder ⇒ Ordinary year
• Option - (4) : 2020 → (2020 ÷ 4) = 0 Remainder ⇒ Leap year

Thus, out of all the options '2014' is not a leap year.

Hence, "2014" is the correct answer.

Additional Information Leap year → To determine if a year is lea ap year, the year is divisible by (4) except for the end of the century years, which much also be divisible by 400.
