Tim Harford has been retweeting this little puzzle as part of a discussion with @paullewismoney:
Reminds me of an old riddle, Paul. Which weighs more, a pound of gold or a pound of feathers? You will know the answer…
Thanks all tweets re: @paullewismoney and whether a pound of gold weighs more than a pound of feathers. Most of you are wrong…
…but @adam_j666 @andrew_F_smith and @cleverwithmoney have it right. Congrats. And I’m sure @paullewismoney had it right.
The answer is a pound of feathers weighs more than a pound of gold. But an ounce of feathers weighs less than an ounce of gold…
…Gold weighed in troy ounces (31.1g) with 12 to pound = 373.24g. Feathers weighed avoirdupois oz (28.35g) x 16 to pound = 453.59g.
