To find out the answer of this question we have to perform following calculation. 7 ) 365 ( 52 35 ----- 15 14 ---- 1 The reminder is 1, i.e.,Monday. But, using this method, it is very critical to find out the day of 1st January of 1988. So, we have an another idea. Find out how many Leap years are present before current year. Suppose it is L . So, L = y/4 If Current year is...
