Problem Solving (PS) | Re: At a certain fruit stand, the price of each apple is 40 cents and the

The current average is 56.

That's closer to 60 than to 40.

What percent could be oranges ? 75 ?

75% would be 45 for the oranges and 25% of 40 or 10 for the apples, total

55 cents. 1 cent short.

80% oranges would be 48 cents, so 20% apples would be 8 cents.

Total 56 cents. So 8 oranges, 2 apples.

Some oranges are removed to achieve 52 cent average.

How is 52 cents achieved as an average ? Just like before.

How about 60% oranges equals 36 cents, leaving 40% apples or 16 cents. Total:52 cents.

Apples stay the same number 2 and they're now 40% of the total. So the total must be:

2/.4 = 5

Since there were 10 fruits before and now 5, 5 oranges must have beenremoved.
