**Reiny**, Sunday, March 3, 2013 at 12:23amI made a Venn diagram with 3 intersecting circles T, D, and H

I labeled the intersection of all 3 as x, our unknown.

I labeled the part consisting only of T and D (no x) as a

I labeled the part consisting only of T and H as b

I labeled the part consisting only of D and H as c

so a+b+c = 20 , according to my interpretation

65 + 76-b-x + 53-a-x-c = 100

194 - (a+b+c) - 2x = 100

194 - 20 - 2x = 100

-2x = -74

x = 37

so 37 are tall , dark and hansome
