Since Bill starts training on the first Monday of a month that begins on a Thursday (1st), bill will actually start cycling on 5th of the month (1st Monday).

Total miles for the week=3+4+7+11+1+12=38
total weeks = 3 since 21 days
so 38*3 = 114

Since he starts biking from Monday , by the time he reaches the 21st day of the month he would have driven for two weeks and three days. He already lost 4 days in the beginning. hence 38 x 2 + (M + Tue +Wed) =76+18=94

OE seems to be wrong here as it has not considered that 21st of that minth will not have 3 entire M-S weeks. Since the month began on thursday so, 21 will Wednesday and hence answer should consider 2 weeks and 2 days. 83 hrs is the answer acc to that.

IMO D is the ans
