Price of peeled oranges

Question

The peel of an oorange weighs about 1/6 the mass of the whole orange. The cost of six oranges is $4.80. All the oranges were peeled and the fruit was found to weigh 1.6kg. What was the price per kilogram of the peeled oranges?

Answer 1

You are paying $4.80/6 = $0.80 = 80 cents per orange including the peel.

Since 1/6 of that is the peel, then 5/6 * 80 = 400/6 = 200/3 = 66 + 2/3 cents

for the orange without the peel.

13+1/3 cents is wasted on the peel
