The last day of a century cannot be
Pick one
A) Monday B) Wednesday C) Tuesday D) Friday E) None of these
Explanation :   We know that number of odd days in 100 years = 5   Hence last day of the first century is Friday   Number of odd days in 200 years = 5 x 2 = 10 = 3 (As we can reduce multiples of 7   from odd days which will not change anything)   Hence last day of the 2nd century is Wednesday   Number of odd days in 300 years = 5 x 3 = 15 = 1 (As we can reduce multiples of 7   from odd days which will not change anything)   Hence last day of the 3rd century is Monday   We know that umber of odd days in 400 years = 0. (? 5 x 4 + 1 = 21 = 0)   Hence last day of the 4th century is Sunday   Now this cycle will be repeated.   Hence last day of a century will not be Tuesday or Thursday or Saturday   Answer : Option Tuesday
