Answer:
The number of unemployed persons is 15 if we assume the person who are looking for work are NOT “unemployed”
The number of unemployed persons is 25 if we understand “looking for work” is “unemployed currently”
Explanation:
If we assume the person who are looking for work are NOT “unemployed” then:
Total 100 people = 60 of whom hold jobs + and 15 of whom are retired + 10 of whom are looking for work + unemployed persons
⇒ unemployed persons = 100 – 60 - 15 – 10 = 15
However, it’s better to understand “looking for work” is “unemployed currently”, then
Total 100 people = 60 of whom hold jobs + and 15 of whom are retired + unemployed persons (including whom looking for work)
⇒ unemployed persons = 100 – 60 - 15 = 25
