Answer 2

Problem Analysis

To solve this problem, we need to compare the amount of grain harvested by Farmer Sidorov, Farmer Petrov, and Farmer Ivanov. We are given that Farmer Sidorov harvested 20% less grain than Farmer Petrov, and Farmer Ivanov harvested 40% more grain than Farmer Petrov. We need to find the percentage by which Farmer Ivanov harvested more grain than Farmer Sidorov.

Solution

Let's assume that Farmer Petrov harvested 100 units of grain.

According to the problem, Farmer Sidorov harvested 20% less than Farmer Petrov. Therefore, Farmer Sidorov harvested 80 units of grain (100 - 20% of 100).

Similarly, Farmer Ivanov harvested 40% more than Farmer Petrov. Therefore, Farmer Ivanov harvested 140 units of grain (100 + 40% of 100).

To find the percentage by which Farmer Ivanov harvested more grain than Farmer Sidorov, we can calculate the percentage increase as follows:

Percentage Increase = ((Ivanov's Harvest - Sidorov's Harvest) / Sidorov's Harvest) * 100

Substituting the values, we get:

Percentage Increase = ((140 - 80) / 80) * 100 = 60%

Therefore, Farmer Ivanov harvested 60% more grain than Farmer Sidorov.

Answer

Farmer Ivanov harvested 60% more grain than Farmer Sidorov.
