If the seventh day of a month is three days earlier than a Friday, what day will be the nineteenth day of the same month?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Sunday
The weekday repeats every 7 days, so a date 7, 14 or 21 days later falls on the same day, and only the days left over after whole weeks move the weekday forward.
Three days earlier than Friday is Tuesday, so the 7th is a Tuesday
From the 7th to the 19th is \(19-7=12\) days \(=1\) week \(+\,5\) days
Tuesday \(+\,5\) days \(=\) Sunday
