If 20 March 2001 is a Tuesday, then what will the day of the week be on 23 April 2021?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Friday.
The number of years is: 2001−2021 = 20
Leap years are 2004, 2008, 2012, 2016, 2020.
Number of normal years: 20 - 5 = 15
Days in March (after 20th): 31 − 20 = 11
Days in April (up to 23rd): 23
Total odd days = {(5 × 2) + (15 × 1) + 11 + 23} ÷ 7 = (25 + 11 + 23) ÷ 7 = 3
Tuesday + 3 days = Friday
23 April 2021 will be a Friday.
