peter paul pam pat

1+x x 1+y y

peter+paul+pam+pat 60

peter+paul pam+pat+10

1+x+x+1+y+y 60

1+x+x 1+y+y+10x+y 29

x-y 9

so from the two equations we get x 19 and y 10

so peter picked 20 balls

RE: Four persons picking balls. Peter one more than...
Add the given two equations:

2peter + 2paul 70---------(1)

peter picks one ball more than paul

so (1) becomes 2

(1+paul) + 2paul 70

paul 17

if paul 17 put this in (1)

peter becomes 18

Answer can be verified after finding pam and pat.

pam is 13 and pat is 12
