20 Golden rings
King Ratticus was coming up to his 20 th birthday. He decided
he wanted a special treat so he called for Goldie, his
goldsmith, who could make anything out of gold.
"Goldie, I want you to make me 20 gold rings, one for each
year of my life, and one for each finger and toe. Oh, and by
the way, see Queen Ratticus for payment."
Goldie went away and made the 20 gold rings. He then went
to see the Queen for payment.
"Well, Goldie, they are excellent, but how much will they
cost?" asked the Queen.
"My dear Queen, they are not cheap!" said Goldie, "they are
one million pounds in all….or you could pay £1 for the first
ring, £2 for the second, £4 for the third, £8 for the fourth
and so on, doubling the cost for each ring."
" I can't afford a million pounds," said the queen, "so I will
pay by the second way, it will be much cheaper!"
Was she right ?
Did she save money or
not?
How much did it cost
her?
