Arjun’s birthday falls on 3rd June. In 2005 he celebrated it on a Friday. On which day of the week will he celebrate his birthday in 2021?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Thursday
A date moves 1 day forward after each ordinary year and 2 days forward after a year that contains a 29th February.
From 3 June 2005 to 3 June 2021 there are 16 years
29th February comes in between in 2008, 2012, 2016 and 2020, so 4 extra days
Odd days \(=16+4=20=2\times7+6\), that is 6 odd days
Friday + 6 days = Thursday
