Let the common factor = x
then core section has 7x pages
and advance section 2x pages
Total pages = 450
7x+2x=450
9x=450
x=450/9
x = 50
Core section = 7x =7*50 = 350 pages
Advance Java section = 2x = 2*50 =100 pages
then core section has 7x pages
and advance section 2x pages
Total pages = 450
7x+2x=450
9x=450
x=450/9
x = 50
Core section = 7x =7*50 = 350 pages
Advance Java section = 2x = 2*50 =100 pages
