Answer 2

Calculating Starch Yield from Potatoes

To calculate the amount of starch obtained from a given quantity of potatoes, we can use the provided information.

Given: - 150 grams of potatoes yield 27 kg of starch.

Calculation: To find out how much starch can be obtained from 420 kg of potatoes, we can use the following proportion: 150 grams is to 27 kg as 420 kg is to x (the unknown amount of starch).

Using the proportion, we can calculate the amount of starch obtained from 420 kg of potatoes: 150g/27kg = 420kg/x

Solution: x = (27kg * 420kg) / 150g x = 75.6 kg

Answer: From 420 kg of potatoes, approximately 75.6 kilograms of starch can be obtained.

Amount of Potatoes Needed for 30.6 kg of Starch

To find out how much potatoes are needed to obtain 30.6 kg of starch, we can use the given information.

Given: - 150 grams of potatoes yield 27 kg of starch.

Calculation: To find out how much potatoes are needed to obtain 30.6 kg of starch, we can use the following proportion: 150 grams is to 27 kg as y (the unknown amount of potatoes) is to 30.6 kg.

Using the proportion, we can calculate the amount of potatoes needed to obtain 30.6 kg of starch: 150g/27kg = y/30.6kg

Solution: y = (150g * 30.6kg) / 27kg y = 170g

Answer: To obtain 30.6 kg of starch, approximately 170 grams of potatoes are needed.

These calculations are based on the provided information and should give a good estimate of the starch yield from potatoes and the amount of potatoes needed to obtain a specific quantity of starch.
