Question

On an average, each page contains 28 lines to fill some content in a book containing 300 pages. How many lines should a page contain if the same content has to be filled in 280 pages?​

Answer 1

Answer:

Number of pages and lines are in inverse proportion.

Let the number of pages contain if the same content has to be filled in 280 pages be x.

So

$28 \times 300 = x \times 280 \\ \\ x = \frac{ \cancel{28} \times \cancel{300} \: \: ^{30} }{ \cancel{280} \: \: ^{ \cancel{10}} }$

Hence 30 lines is the answer
