  D. 
N =pm

faiqraees · Answer

consider p as speed at which he can read
n the number of pages
and m the time
now look in a logical way 
if his speed is 1 page in 1 hour so he can read exactly 1 page in 1 hour
if his speed is 3 page in 1 hour, he can also read exactly 6 pages in 2 hour
from this you can make an equation
since we know we are getting the total number of pages by multiplying time and speed we can make an equation where 
n=.......?
