Answer:
Explanation:
Given that :
- Tim has read 30 % of a book.
- He has 56 more pages to finish.
to find :
- How many pages are there in the book ?
let us assume :
- total pages of book is 100•/•
explanation :
⟼ total book = 100•/•
⟼ Tim has read 30 % of a book.
⟼ 100 - 30 •/• = 70 •/•
⟼ 70 •/• = 56 pages
⟼ 1 •/• = 56 / 70
⟼ 100 •/• = 56 / 70 × 100
⟼ 100 •/• = 56 / 7 × 10
⟼ 100 •/• = 8 × 10
⟼ 100 •/• = 80 pages
∴ tim has 80 total pages in book.
