Question

Find the day of the week on $\text{15 August, 1947}$

• A. Thursday.
• B. Friday
• C. Monday
• D. Tuesday

Answer 1

The correct option is A Thursday.

$\Rightarrow 1600$ year has $0$ odd days .....(i)
$300$ years have $1$ odd day .....(ii)
$46$ years have $11$ ;eap years and $35$ ordinary years.
$\therefore (11\times 2+35)=57\text{odd days}=1\text{odd day}$
Till $\text{30 June}$ there are $6$ odd days
From $\text{1st July to 15 August}$ there are $46$ days, i.e., $4$ odd days
$\therefore 0+1+1+3=5$ odd days
$\therefore$ the day will be Thursday.
