Question

Reading 20 pages of a book daily, it is completed in 15 days. In how many days, will the book completed if the number of pages read daily is 5​

Answer 1

Answer:

From the question,

Number of days taken to finish the book if she reads 18 pages every day =25

Number of days taken to finish the book if she read 1 page every day =(18×25)

∴ Number of days taken to finish the book if she reads 15 pages every day =(18×25)/15

=30 days

Answer 2

Here, this is Indirect variation.

x1y1 = x2y2

15×20 = 5×y2

y2 = 300/5

y2 = 60

Hence, the book will completed in 60 days if the number of pages read daily is 5.
