Question 276139
Let's start with 60 and whittle down from there.
1 in 3 say money tied up. So that means {{{2/3}}} have some money
{{{60 * 2/3 = 40}}} with money
2 of 5 tell him, no way. So that means 3/5 are still listening
{{{40 * 3/5 = 24}}} 
1 in 2 won't lend on principle. So 1/2 may
{{{24 * 1/2 = 12}}}
He still has a chance with 12 of them

Good luck Bob
