If 13 January 2023 is a Monday, then what day will 14 December 2023 be?

Given: If 13 January 2023 is a Monday.

Solution:

We need the day on 14 December 2023

Count total days between dates:

From 13 Jan to 14 Dec 2023.

Days remaining in Jan = 18
Then months:

Feb = 28

Mar = 31

Apr = 30

May = 31

Jun = 30

Jul = 31

Aug = 31

Sep = 30

Oct = 31

Nov = 30

Dec (up to 14) = 14

Total = 18 + 28 + 31 + 30 + 31 + 30 + 31 + 31 + 30 + 31 + 30 + 14 = 335 days

335 ÷ 7 = remainder 6

So, move 6 days ahead from Monday:

Tuesday (1), Wednesday (2), Thursday (3), Friday (4), Saturday (5), Sunday (6)

So, Sunday will be 14 December 2023.

Thus, correct option is (b).
