Sonu was born on June 15, 1992, on what day of the week was he born?

Correct option is C

As we know-
Total no of odd days in 100 years = 5
Total no of odd days in 200 years = 3
Total no of odd days in 300 years = 1
Total no of odd days in 400 years = 0
Given date is 15 June 1992
Total no of odd days till 1991 = 1600 + 300 + 91 ( in 91 year = 22 leap year and 69 ordinary year)
= 0 + 1 + 22 2 + 69 1
= 1 + 44 + 69
= 114
Total no of odd days from 1st Jan 1992 to 15 June 1992 = 31 + 29 + 31 + 30 + 31 + 15 = 167 (1992 is a leap year so February will be 29 days)
Total no of days till 15 June 1992 = 114 + 167 = 281
when we divided 281by 7 then the remainder will be 1
So, Sonu was born on 15 June 1992 that was Monday.
Correct answer is (c) Monday.
