Adding all of them comes 55. So there are 55 people who cannot speak alteast one language. Remaining 45 people can speak all the three languages. It is logically very good puzzle!!! Thanks for such stuff 10 peoples cannot speak spanish, 20 people cannot speak Italian and 25 cannot speak mandrin. Adding all of them comes 55.

I don't think the writer intended it, but the way the question was phrased, it is asking for the minimum of speakers that can speak all three languages. That being 1. the work "atleast" is key. pjsk8 is right.

the work “atleast” is key.

20 cant speak italian
25 cant speak mandarin
so
100 – (10+20+25)= 45
can speak 3 languages

10 don’t speak spanish
25 don’t speak mandarin
20 don’t speak italian
therefore the rest speak all languages – 45 … if that makes sense

Population = 100 Within the population, Spanish Speakers = 90 Italian Speakers = 80 Mandarin Speakers = 75 So, for the minimum number of all three language speakers or total overlap... x = 90 - (100 - 80) - (100 - 75) Used same method as The Science Pundit.

Population = 100
Within the population,
Spanish Speakers = 90
Italian Speakers = 80
Mandarin Speakers = 75

So, for the minimum number of all three language speakers or total overlap…

x = 90 – (100 – 80) – (100 – 75)
