Answer 2

Answer:

60 pages

Step-by-step explanation:

let book had ‘x’ no. of pages

so, pages read on first day = 3/8 of x = ( 3/8)x = 3x/8

remaining = x-(3x/8) = (8x-3x)/8 = 5x/8

and; Pages read on second day = (5x/8)(4/5) = x/2

remaining = x-(x/2) = (2x-x)/2 = x/2

also, remaining = 30 pages

so, x/2 = 30

or x = 30*2

or x = 60

so, the book had 60 pages
