Question page →Q5 · Reasoning · Clocks & Calendars
Which of these years is a leap year: 1800, 1911, 2128, 1951?
- A. 1800
- B. 1911
- C. 2128
- D. 1951
Show answer
Answer: C. 2128
A year is a leap year if it divides exactly by 4, except century years, which must divide exactly by 400. 2128 divides by 4 and is not a century year, so it is a leap year. 1800 is a century year that does not divide by 400, so it is not a leap year, and the others do not divide by 4.
