Sonu was born on June 15, 1992, on what day of the week was he born?
Tuesday
Wednesday
Monday
Sunday
Correct answer
Monday
Why this answer is correct
Given date: 15 June 1992.
| Year | Odd Days |
|---|---|
| 100 | 5 odd days |
| 200 | 3 odd days |
| 300 | 1 odd days |
| 400 | 0 odd days |
Now,
Till 1991 → 1600 + 300 + 91
| Leap Year | 2 Odd days |
|---|---|
| Ordinary Year | 1 Odd day |
In 1600 Years the odd day is 0,
In 300 Years the odd day is 1,
In 91 Years(22 Leap Years and 69 Ordinary year) the odd day is 22 × 2 + 69 × 1 = 44 + 69 = 113 odd day ,
⇒ 0 + 1 + 113
⇒ 114 odd days.
And, from 1st Jan 1992 to 15 June 1992:
⇒ 31(Jan) + 29(Feb, 1992 is a leap year) + 31(March) + 30(April) + 31(May) + 15(June) = 167 days.
Total odd days → 114 + 167 = 281days = 281/7 = 40 weeks and 1 odd days.
→ 1 represents Monday.
So, Sonu was born on June 15, 1992 that was Monday.
Hence, the correct answer is "Monday".
