On what dates of April 2009 did Thursday fall
Answer with explanationAnswer: Option C
We first find the day of the week on 1st April 2009.
1st April 2009 means, 2008 years 3 months and 1 day
= 2000 years + 8 years + January + February + March + 1st April
= 0 odd days + 2 leap years + 6 ordinary years + 31 days + 28 days +31 days + 1 day
= 0+ 4 odd days + 6 odd days + 3 odd days + 0 odd days +3 odd days + 1 odd day
=17 odd days = 3 odd days
From the date in the above problem, when number of days is 3, the day of the week becomes Wednesday.
Thus, first Thursday falls on 2nd April.
In that month, Thursday falls on 2nd, 9th, 16th, 23rd, and 30th.
