Tanvi joined a yoga class on a Friday. She completed her course exactly 333 days later. On which day of the week did she complete the course?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Tuesday
Every 7 days the same weekday comes back, so only the days left over after whole weeks (the odd days) move the weekday.
\(333=47\times7+4\), so 4 odd days
Friday + 4 days: Saturday, Sunday, Monday, Tuesday
