Question

If 31st july ,1993 was friday, then what will be the day on 31st july,2001?

Answer 1

it will be Tuesday please mark it brainliest answer

Answer 2

number days between 31st july ,1993 and 31st july,2001 = sum of daysin each year = 153 + 365 + 365 + 366 + 365 + 365 + 365 + 366 + 213 = 2923
 7 days make a week.. so 
 $\frac{2922}{7} =417\frac{3}{7}$
 hence friday + 3 = Monday

 another way.. 
 every year 365 days =52 weeks + 1days hence 
'94.... it's saturday
'95....sunday
'96....tuesday (∵1996 is a leap year add a day more)
'97.... wednesday
'98.... thrusday
'99.... friday
2000... sunday
'01.... monday

FYI...31st july ,1993  was saturday not friday LOL
