Step-by-step explanation:
let the total pages be x
on one day he reads 2/7 of x=2x/7
on next day he reads 5/16 of x=5x/16
the unread pages=275
A/Q
2x/7+5x/16+275=x
(32x + 35x/112)+275=x
(67x/112)+275
67x + 30,800/112=x
67x + 30,800=112x
67x-112x= -30,800
-45x=-30, 800
-x=-30,800/45
-x=-6160/9
or x=6160/9 Ans
I hope it will help you
