Correct Answer: Friday

Solution : Code for months –

Code for days –

Code for centuries –

For, 24th of August 1923 –
Formula: {Date + (Month code) + (Century code) + ( last two digit of the year) + ((last two digit of the year / 4)'s Quotient)} / 7

Date = 24
Code for the month (August) = 2
Code for the century (1900) = 0
(1923 = 1900 + 23; For 1900 it will be 0 and for 23 it will be 23)
And, 23 ÷ 4 = 5(Quotient)
Now, on adding them we get→24 + 2 + 0 + 23 + 5 = 54
On dividing 54 by 7, we get 5 as a remainder.
5 is the code for Friday.

So, the 24th of August 1923 will be Friday. Hence, the fourth option is correct.
