If 01 March 2012 was Thursday, then what was the day of the week on 01 February 2016?
Explanation:
From 1 March 2012, till 1 March 2013 there will be 1 odd day. From 1 March 2013, till 1 March 2014 there will be 1 odd day. From 1 March 2014, till 1 March 2015 there will be 1 odd day. ∴ Total 3 odd days so far.
Now, let us count days after 1 March, 2015 till 1 Feb, 2016. March - 30 more days April - 30 May - 31 June - 30 July - 31 August - 31 September - 30 October - 31 November - 30 December - 31 January - 31 February - 1
∴ Total 337 days ⇒ Odd days = Remainder of 337/7 = 1
∴ Total odd days From 1 March 2015, till 1 Feb 2016 = 3 + 1 = 4.
∴ 1 Feb, 2016 will be 4 days after Thursday i.e., Monday.
Hence, option (b).
