Question

Which weighs the most, a pound
of feathers or a pound of gold? The solution is not that they
both weigh the same!

Answer 1

The answer to your question is that a pound of feather weighs more than a pound of gold.

Answer 2

The pound of feather would weigh more , coz here pound  refers not to the weight but to the currency. The weight of the gold you buy of 1 pound would be less than the weight of feathers you buy for 1 pound.
