Question

Aiden borrows a book from a public library. He read a few pages on day one. On day two, he reads twice the number of pages than he read on day one. On the third day, he reads six pages less than what he read on the first day. If he read the entire book that contains 458 pages in three days, how many pages did he read on day three?

Answer 1

Let day 1 = x pages. Then day 2 = 2x and day 3 = x − 6.
Sum: x + 2x + (x − 6) = 4x − 6 = 458 → 4x = 464 → x = 116.
Day 3 = 116 − 6 = 110 pages.
