We collected 100 kg of mushrooms, the moisture content of which was 99%. When the mushrooms were dried, their moisture content dropped to 98%. What was their weight?

Let X kilogram be the mass of mushrooms with a moisture content of 98%. The percentage of the substance in the mass of a mushroom with a moisture content of 99% is 1%, and in a mass of mushrooms with a moisture content of 98% – 2%.

Let’s compose and solve the proportion:

100 kg – 1%;

X kg – 2%;

Inversely proportional relationship:

100 * 1 = 2 * X;

100 = 2X;

X = 50.

Answer: 50 kilograms.
