Correct Question -

Rahul reads 20 pages of a story book everyday and finishes it in 12 days .

Ram is a slow reader and can read only 15 pages per day .

He works for two days then he was joined by b .

Find the total time taken to finish the work?

Solution -

In the above question , It is mentioned that -

Rahul reads 20 pages of a story book and finishes it in 12 days .

Number of pages present in that story book :

> 20 × 12

> 240 pages .

Ram is a slow reader and can read only 15 pages per day .

He works for 2 days .

Number of pages read by him in these days -

> 30 pages

Remaining pages > 240 pages - 30 pages = 210 pages.

Let b read x pages per day .

The total number of pages read by both of them in a day -

> 15 + x .

Number of days required to reach 210 pages -

> 210/(x+15) pages

This is the required answer.
