Question

Hari reads $22$% of the pages of a book on the first day , $53$% on the second day and $15$% on the third day. If the number of pages remaining to be read is $30$ , find the total number of the pages.

Answer 1

The percentage of the pages read $=22+53+15=90$%

The percentage of the pages to be read $=100-90=10$%

Let the number of pages in the book be 'x'

Give $10$% of 'x' is $30$

$\frac{10}{100}\times x=30$

$x=30\times 10=300$

$\therefore$ The number of pages in the book is $300$
