I am a bit confused. How do you interprent the statement: "All invested in C invested in A"? How do you interpret this in the Venn diagram?

I get more than 60 as well

People in A 48 (14 only A, 7 in AB, 15 in AC, 12 in ABC)

People in B 36 (17 only B, 7 in AB, 0 in BC, 12 in ABC)

People in C 27 (0 only C, 0 in CB, 15 in AC, 12 in ABC)

That gives a total of 65 people???
