SSC CGL - 16 Aug 2021 - Shift 1 • Reasoning • Q81

What was the day of the week on 17 April 2014?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. Thursday.

Day Sun Mon Tue Wed Thu Fri Sat
Code 0 or 7 1 2 3 4 5 6

 

17th April, 2014 = 2013 years + Number of days from 1.1.2014  to 17.04.2014

Odd days in 1600 years = 0, Odd days in 400 years = 0

13 years = (10 ordinary years + 3 leap years) = (10 × 1 + 3 × 2) = 16/7; R = 2

Therefore, the number of Odd days = 2

Jan   Feb    Mar     Apr

31  + 28  +  31  +  17 = 107 days

Therefore, 107 days = (15 weeks + 2 days) → 2 odd days

Total number of odd days = (0 + 0 + 2 + 2) = 4 odd days
