A bag with apples has a mass of m-2.5 kg. The package contains N = 10 identical apples. Determine the mass of one apple. By what percentage did the weight of the bag of apples decrease after two apples were eaten? Disregard the weight of the empty bag.

m = 2.5 kg.

N = 10.

N1 = 2.

m1 -?

The mass of the package with apples m is the sum of all apples in the package. Since there are N apples in the package, the mass of one apple m1 will be determined by the formula: m1 = m / N.

m1 = 2.5 kg / 10 = 0.25 kg.

Let’s find the mass m2 of apples in a bag after eating N1 apples.

m2 = m – N1 * m1.

m2 = 2.5 kg – 2 * 0.25 = 2 kg.

m – is 100%

Let’s find x what percentage is the mass m2.

x = m2 * 100% / m.

x = 2 kg * 100% / 2.5 kg = 80%.

x “= 100% – 80% = 20%.

Answer: m1 = 0.25 kg, the weight of the package has decreased by x “= 20%.
