Answer :
g=number of words on george's page
b=number of words on bill's page
c=number of words on charlie's page
george has 2 times as many as bill's age
g=2b
bills contains 50 less than charlie
b=c-50
if each person can type 70 words per minute, after 1 minute (that is an additional 70 words for each person)
the difference between twice nmber of words on bill's page and the number of words on charlie's page is 220
so
that is after increase of 70 words
2(b+70)-(c+70)=220
and
b=c-50
subsittute
2(c-50+70)-(c+70)=220
2(c+20)-c-70=220
2c+40-c-70=220
c-30=220
c=250
charlie had 250 initially
b=c-50
b=250-50
b=200
bill had words 200 initially
