Rita’s birthday falls on 15th October. In 2002 she celebrated it on a Tuesday. On which day of the week will she celebrate her birthday in 2024?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Tuesday
A date moves 1 day forward after each ordinary year and 2 days forward after a year that contains a 29th February.
From 15 October 2002 to 15 October 2024 there are 22 years
29th February comes in between in 2004, 2008, 2012, 2016, 2020 and 2024 (29 February 2024 is before 15 October 2024), so 6 extra days
Odd days \(=22+6=28=4\times7\), that is 0 odd days
So the birthday falls on the same day, Tuesday
