Explanation
This is a pattern problem. An efficient method is to recognize that the 7th day after the initial deposit would be Tuesday, as would the 14th day, the 21st day, etc. Divide 100 by 7 to get 14 full weeks comprising 98 days, plus 2 days left over.
For the two leftover days, think about when they would fall. The first day after the deposit would be a Wednesday, as would the first day after waiting 98 days. The second day after the deposit would be a Thursday, and so would the 100th day.

Note that 7 days after he deposits the money, it is again Tuesday, and every number of days that is a multiple of 7 will again be Tuesday. Thus, we see that 7 x 14 = 98 days later it is a Tuesday. Thus, the 99th day is Wednesday, and the 100th day is Thursday.
Answer: D
