Correct Answer: Saturday

Solution : Code for months –

Code for days –

Code for centuries –

For, 1st of January 2033 –
Formula: {Date + (Month code) + (Century code) + ( last two digit of the year) + ((last two digit of the year ÷ 4)'s Quotient)} ÷ 7

Date = 1
Code for the month (January) = 0
Code for the century (2000) = 6
(2033 = 2000 + 33; For 2000 it will be 6 and for 33 it will be 33)
And, 33 ÷ 4 = 8(Quotient)
Now, on adding them we get→1 + 0 + 6 + 33 + 8 = 48
On dividing 48 by 7, we get 6 as a remainder.
6 is the code for Saturday.

So, the 1st of January 2033 will be Saturday. Hence, the first option is correct.
