Which of the following years is not a leap year?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 1500
An ordinary year is a leap year when it is divisible by 4. A century year (one ending in 00) is a leap year only when it is divisible by 400.
Option (1) 1200 — a century year; \(1200=3\times400\), a leap year
Option (2) 2400 — a century year; \(2400=6\times400\), a leap year
Option (3) 1500 — a century year; \(1500\div400=3.75\), not a whole number, so 1500 is not a leap year
Option (4) 1996 — \(1996=4\times499\), a leap year
