31st July 2001
31st July 1993
--------------------------
8 year . But between 31st July 1993 to 31st July 2001 , two leap years 31st July 2000 present .
so, 2 years = 2× 366 days
7 years = 365 × 7 days
total number of says = 365×6 + 366×2 =2922 days
again, we know, 52 week in on year
so, number of week in 8 years = 52 × 8 = 416 week , so number of days according to week = 416 × 7 = 2912 days .
Hence, number of day left = 10
it means we can include one more week then, left days = 3
now counting start after Friday:
Saturday , Sunday, Tuesday
Hence, final day comes , Monday .
Hence, Monday is absolutely right answer.
