Question

Виноград при сушке теряет 65% своей массы Сколько изюма получится из 400 килограмм, 350кг, 1,8 тонн свежего винограда?

Answer 1

400-400:100х65=140кг
350-350:100х65=122,5кг
1800-1800:100х65=630кг

400 кг отнимаем [400:100 (находим 1%)х65=260 (это 65% потеря)]= 140 (полученные 35%)

Answer 2

Calculating Raisin Yield from Grapes

When grapes are dried, they lose about 65% of their mass. Let's calculate the amount of raisins that can be obtained from the given quantities of fresh grapes.

1. From 400 kilograms of fresh grapes: - 65% of the mass is lost during drying. - Therefore, the remaining mass after drying is 35% of the original mass. - The amount of raisins obtained from 400 kilograms of fresh grapes after drying is: ``` 400 kg * 0.35 = 140 kg ```

2. From 350 kilograms of fresh grapes: - Using the same logic, the amount of raisins obtained from 350 kilograms of fresh grapes after drying is: ``` 350 kg * 0.35 = 122.5 kg ```

3. From 1.8 tons (1 ton = 1000 kilograms) of fresh grapes: - Converting 1.8 tons to kilograms: ``` 1.8 tons * 1000 kg/ton = 1800 kg ``` - The amount of raisins obtained from 1.8 tons of fresh grapes after drying is: ``` 1800 kg * 0.35 = 630 kg ```

So, the amount of raisins obtained from 400 kilograms, 350 kilograms, and 1.8 tons of fresh grapes after drying would be 140 kg, 122.5 kg, and 630 kg, respectively.
