Answer 2

Step-by-step explanation:

let total number of pages in a book

read book by Rajesh first day

$x \times \frac{3}{8} = = \frac{3x}{8}$

$x \times \frac{4}{5} = \frac{4x}{5}$

there are 30 pages of left

$x- ( \frac{3x}{8} + \frac{4x}{5} )$

$x- ( \frac{15x + 24x}{40} ) = 30$

$\frac{x}{40} = 30$

$x = 40 \times 30 \\ \\ x = 1200$

$x- \frac{39x}{40} = 30$

$\frac{40x - 39x}{40} = 30$
