Question 350734

6000 computers total every third one has a hardware problem that's 1/ 3 of them so 6000/3= 2000
6000 computers total every fourth one has a software problem that's 1/4 of them 6000/4=1500
6000 computers total every tenth one has a cosmetic problem that's 1/10 of them = 600
2000+1500+600= 4100
6000-4100= 1900 shipped
