Answer 2

Answer:

The correct answer is option C

Step-by-step explanation:

We have to find, pt of all the day on pt Dec, 1984. 1st Dec 1984 means (1983 years 11 months and day)

Now,

1900 years have 1 odd day

83 years have (20 leap years and 63 ordinary years)

$=(40+63)$ odd days

$=103$ odd days

$=5$ odd days

11 months and 1 day

Jan Feb Mar Apr May June July Aug Sep Oct Nov Dee

$\begin{array}{llllllllllll}31 & 29 & 31 & 30 & 31 & 30 & 31 & 31 & 30 & 31 & 30 & 1\end{array}$

$=336$ days $= > 0$ odd day

Total no. of odd days

$=(1+5+0)=6$

Hence, it was Saturday on 1st Dec 1984 and 1st Sunday was on 2nd Dec 1984. Subsequently,

Sunday's of the month were on 2nd, 9th, 16th, 23rd and 30th.
