Detailed Solution
Download Solution PDFGiven: Leela's birthday falls on Wednesday, 12th May.
According to the question, Priya was born on 14th December in the same year as Leela:
So, The number of odd days from 12th May to 14th December:
| Year | Period | Calculation | Odd days |
| Same year | 12 May - 14 December | 19 May + 30 June + 31 July + 31 August + 30 September + 31 October + 30 November + 14 December = 204 days | 216 ÷ 7 = 6 |
| Total odd days | 6 | ||
So, six odd days will be added to Wednesday because the day is asked in future.
∴ Tuesday was the day of the week on 14th December.
Hence, "Option 3" is the correct answer.
Additional Information
| No. of odd days | Ordinary year | Leap year |
| 365 ÷ 7 = 52 weeks + 1 odd day |

| Years | No. of odd days |
| 100 | 5 |
| 200 | 3 |
| 300 | 1 |
