Question

When we add days every year 4 times in a row, we get an extra day after every 4 years which is called a leap year.

• A. 0.5
• B. 0.25
• C. 0.75
• D. 1.25

Answer 1

The correct option is B 0.25

When we add a number 4 times, it should add to 1 (day)
So, $\frac{1}{4}$ = 0.25 and $4\times 0.25=1$.
Hence, when we add 0.25 days every year four times in a row, we get an extra day.
