C. r - 1000
D. 1000r
E. (0.2)(5000 - r)
Total people = \(5000\), People with bond no stock =\(a\) & People with stock no bond = \(r\)
People with only bond or only stock = \(20%\) of \(5000=1000\)=\(a+r\)
Hence \(a\)=People with bond no stock=\(1000-r\)
Hence I would go for option B.

Hi im a little confused, why can't people have both bond and stocks in this group of 5000 people i.e the remaining 4000 people. The question does not explicitly say that there are none who don't? Please help, i think i'm missing something..
