Answer 1

The assumption is that everyone makes the same amount,

and it is INVALID!!!

They're trying to TRICK you into the proportion:

1.62% 100 %

------------- = -----------------

2 billion ? billion

Upon cross multiplication, the percents and billions cancel:

1.62 * ? = 200

? = 200/1.62 = 20000/162 = 10000/81 = 123 + 37/81

which to the nearest penny is 123,456,790,123.46
