Of the companies surveyed about the skills they required in prospective employees, 20 percent required both computer skills and writing skills. What percent of the companies surveyed required neither computer skills nor writing skills.

1. Of those companies surveyed that required computer skills, half required writing skills.
2. 45 percent of the companies surveyed required writing skills but not computer skills.

Couldn’t find this problem on the forum so I am curious on how you would go about this.

Thanks,

IMO C.

1) insufficient. Computer skills would be 40% , comp and writing skills are 20%. No info about non-writing and non-computer skills.

2) insufficient. 45% required computer skills but not writing skills. total writing will give us 65%. But no info on non-writing and non-computer skills.

together: 15% would not require either skill.

Check excel sheet.
