Count the days from months between May 1 and August 1 like this: May days = 31;June days = 30;July days = 31; So total days = 92. Since 92 = 13 X 7 + 1, so excess days are 1. So we can count the day to Monday + 1 = Tuesday.

Minutes from 9::42 A.M. to 10::00 A.M. are 60 - 42 = 18. Minutes from 10::00 A.M. to 12::00 noon are 60 X 2 = 120 mins. Minutes from 12::00 noon to 8::12 P.M. are 60 x 8 = 480 + 12 = 492 mins. So total minutes are 18 + 120 + 492 = 630 minutes, which are equal to 60 X 10 + 30 Thus, hours are = 10, and minutes = 30
