A book consists of 30 pages, 25 lines on each page and 40 characters on each line. If this content is written in another note book consisting of 30 lines and 50 characters per line, then the required number of pages will be how much less than the previous pages?

[ A ] 14
[ B ] 20
[ C ] 10
[ D ] 18

Answer : Option C

Explanation :

Let no. of new pages be$ P_ 2$ 30 $\times$ 25 $\times$ 40 = $P_ 2$ $\times$ 30 $\times$ 50

$P_2$ = $1000 \over 50$ = 20

$\Rightarrow$ $P_2$ = 20 pages

So, Required no.of pages = 30 - 20 = 10
