I was shopping for vegetables at the New Market. I saw two
pumpkins of the same quality but of different sizes. One was bigger than the
other. The bigger one was 60 cm in circumference and the other 50 cm. I asked
the times more expensive. Which one do you think would have been a better buy?
Answer: Circumferences are to one another as their
diameters. If the circumference of one pumpkin in 60 centimetres and of the
other 50 centimetres, then the ratio between their diameters is:
60: 50 =6/5 and the radio between their sizes are: (6/5)³ =
216 /125 =1.73
The bigger pumpkin, if it were priced according to its size
or weight should cost 1.73 times or 73 per cent more than the small one. Yet
the vendor has priced it only 50 per cent more. Therefore it is clear, that the
bigger pumpkin is a better bargain.
