If it was Wednesday on April 30 April, 2006. What will be the day on 2 October 2040? |
Thursday Friday Tuesday Wednesday |
Friday |
\(\frac{Date + Month code + Century code + Century upper year + Quotient of Upper year/4}{7}\) \(\frac{30+6+6+6+1}{7}\) \(\frac{49}{7}\) = Remainder 0 means Sunday but here Wednesday is given i.e. 3 days after. We have to find out 02/10/2040 \(\frac{Date + Month code + Century code + Century upper year + Quotient of Upper year/4}{7}\) \(\frac{2+0+6+40+10}{7}\) \(\frac{58}{7}\) = Remainder 2 means Tuesday Therefore, 3 days after Tuesday is Friday which is the correct answer. Note: Code for Mon – 1 Tues – 2 Wed – 3 Thurs – 4 Fri – 5 Sat –6 Sun – 0 Code for Jan – 0 Feb – 3 Mar – 3 Apr – 6 May – 1 June – 4 July – 6 Aug – 2 Sep – 5 Oct – 0 Nov – 3 Dec – 5 Code for 1900 is 0 2000 is 6 2100 is 4 2200 is 2 2300 is 0 2400 is 6 2500 is 4 and Likewise |
