George's page contains twice as many typed words as Bills page and Bills page contains 50 words fewer than Charlie's page. If each person can type 60 words per minute, after one minute the difference between twice the number of words on Bills page and the number of words on Charlie's page is 210.

Let’s assign variable to use in every person in the given situation.

let x be the value of George’s number of words on his page

let y be the value of Bills number of words in his page

and let z be the value of words on Charlie’s page

=> X = 2 (Y)

=> Y = Z - 50

They type 60 words per second.

=> 2Y - Z = 210

Now, let’s start solving:

2Y + 0 - X = 0

Y - Z + 0 = 50

2Y - Z + 0 = 210

Thus the number of Bill’s word number on his page is 260.
