Georges page contains twice as many typed words as bills page and bills page contains 50 fewer words than charlies page. the differenence between twice the number of words on bills page and the number of words on charlies page is 210what is answer

Let
Cp= Charlie's page
Gp= George's page
Bp= Bill's page

To get Charlie's page:
2 (Cp+50)- Cp=210
2 Cp + 100-Cp=210
Cp= 210-100
Cp= 110

to get Bill's page:
Bp=Cp+50
     = 110+50
 Bp= 160

to get George's page
Gp=2(Bp)
     = 2(160)
Gp= 320

therefore:
Cp= Charlie's page has 110
Gp= George's page has 320
Bp= Bill's page has 160
