First, calculate the number of vegetables harvested per square meter in two plots. The first scenario: 540/100 = 5.4kg.

Block 2: 525/100 = 5.25kg.

Then calculate the total number of vegetables:160 * 5.4+240 * 5.25 = 2124.

Calculate the average amount of vegetables harvested per square meter: 2124/(160+240) = 5.31.

Every 100 square meters: 5.31*100 = 531.
