let Core section needs 7x
advance sections needs 2x
sum of the both the sections = 450
7x+2x=450
9x=450
x=450/9
x=50
therefore Core section required 7x i.e 7x50=350 pages
advance java section requires 2x i.e 2x50=100 pages
advance sections needs 2x
sum of the both the sections = 450
7x+2x=450
9x=450
x=450/9
x=50
therefore Core section required 7x i.e 7x50=350 pages
advance java section requires 2x i.e 2x50=100 pages
