Correct Answer: Sunday

Solution : Code for months –

Code for days –

Code for centuries –

For, 14th of March 2010 –
Formula: {Date + (Month code) + (Century code) + ( last two digit of the year) + ((last two digit of the year ÷ 4)'s Quotient)} ÷ 7

Date = 14
Code for the month (March) = 3
Code for the century (2000) = 6
(2010 = 2000 + 10; For 2000 it will be 6 and for 10 it will be 10)
And, 10 ÷ 4 = 2(Quotient)
Now, on adding them we get→14 + 3 + 6 + 10 + 2 = 35
On dividing 35 by 7, we get 0 as a remainder.
0 is the code for Sunday.

So, the 14th of March 2010 will be Sunday. Hence, the first option is correct.
