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

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
