If today is Wednesday, what day will it be 300 days from yesterday?
(A) Monday
(B) Tuesday
(C) Wednesday
(D) Thursday
(E) Friday
The correct answer is A
Explanation: It’s tempting to just make a table and count out the days. Wait, no it’s not—that would require you to write out more than 300 days! Instead, start by unpacking the question: “300 days from tomorrow” really means 299 days from today. Rather than counting out 299 days, think of the pattern of each week. A full week is 7 days, so 7 days from now will be the same day as today. So, all you need to do is figure out how many weeks are completed in 299 days! 299 ÷ 7 = 42.714. Thus 42 weeks would have been completed, and you would be 71.4% through the 43rd week. Figure out what 71.4% of a week is by multiplying it by 7 to get 5 days (.714 x 7 = 5). Thus, the day of the week would be the fifth day after Wednesday, which is Monday. This means choice A is correct.
