Question

Meimei read 250 pages of a book on Friday. She read 75% of the remainder on Saturday and the remaining 125 pages on Sunday. How many pages were there in the book?

Answer 1

Explanation:

x pages in total.

250 pages first.

then

(x - 250)×0.75

is 75% of the remainder after reading the first 250 pages.

as 125 pages were left, that means that they were the other 25% of the remaining pages after reading the first 250 pages.

so,

(x - 250)×0.25 = 125

x - 250 = 125 / 0.25 = 125×4 = 500

x = 500 + 250 = 750

there were 750 pages in the book.

Answer 2

The book had 750 pages.
