Question

Following the current calendar, what will be the day of the week of $1$st January, $2010$?

• A. Friday
• B. Saturday
• C. Sunday
• D. Monday

Answer 1

The correct option is A Friday

Till $2000$, we have $0$ odd days.
Till $2009$ we have $11$ odd days

when diving $11$ by $7$, we get $4$ as remainder

So calculating $4$ days from Monday we get Friday on 1st January, $2010$.

Hence, option A.
