Number of advanced Java sections : number of Core java sections :  = 7 : 2

Number of advanced Java sections = 7 /2 * number of core Java sections
= 7/2 * 2 = 7
Assume that each section contains same number of pages.

Total number of pages = 450
Total number of sections = 7+2 = 9
Pages per section = 450/9 = 50

Pages for Core Java = 50 * 2 = 100
Pages for Advanced Java = 50 * 7 = 350
