. Find the day of the week on 26 January 1950
Odd Days are the days more than the completed days ,
So, the total number of odd days in first 1600 years =0,
The number of odd days in 300 years =1,
So, the number of odd days in the rest of 49 years =( 12×2+37×1)
=5 odd days
Thus the total number of odd days in 1949 =5+1=6 days
In the year 1950
jan 26= 26 days =3 weeks+ 5 days =5 odd days
So, the total number of odd days are 6+5=11 days ,
And the 4th odd day in the week is Thursday.
So,26th jan.1950 is Thursday.
The correct option is D).
