Daryl read 40 pages of a book on Monday and 1/8 of it on Tuesday. He completed the remaining 1/4 of the book on Wednesday. How many pages are there in the book?

Respuesta :

Answer:

the book has 64 pages

Step-by-step explanation:

denoting the number of pages of the book as X then

number of pages read on Monday + number of pages read on Tuesday + number of pages read on Wednesday = number of pages of the book

40 + 1/8*X + 1/4*X = X

40 + 3/8*X = X

40 = X -  3/8*X = 5/8*X

X = 40*8/5 = 64 pages

therefore the book has 64 pages
