a,b,c work in a min=1/8+1/12+1/10=37/120
12 hrs= 12*60 =720 min

number of book printed in 720 min =(37/120)*720=222 books

a.b.c work of a min =1/8+1/12+1/10=0.308
now let x mins taken to print a book
so x*0.308=1
x=3.24 min
no 12 hours=12*60 min=720 min
number of book printed in 720 min = 720/3.24=222.22= 222 books aprox
