Question

5. A girl can finish a book in 25 days if she reads 18 pages of it every day. How many days will
she take to finish it, if she reads 15 pages every day?​

Answer 1

Answer:

Days taken to finish the book if 18 pages are read everyday = 25

Days taken to finish the book if 1 page is read everyday = 18 * 25 [less pages, more days]

Now, days taken to finish the book if 15 pages are read everyday =18*25/15 = 30 [more pages, less days]

Hence, the girl will take 30 days to finish the book if she reads 15 pages everyday..... simply.
