Jason deposits money at a bank on a Tuesday and returns to the bank 100 days later to withdraw the money. On what day of the week did Jason withdraw the money from the bank?

A. Monday
B. Tuesday
C. Wednesday
D. Thursday
E. Friday

The OA is D

Note that after 7 days, we land on the same day, so we have to count how many complete 7-days are there in 100 days.

100 divided by 7 leaves a quotient of 14 and 2 the remainder. So, we must count 2 days from Tuesday. Two days from Tuesday is Thursday.

The correct answer: D

Hope this helps!

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
