Corrosion of less corrosion-resistant metal is usually increased and the attack of the more corrosion-resistant is decreased in galvanic corrosion.

Corrosion of less corrosion-resistant metal is usually increased and the attack of the more corrosion-resistant is decreased in galvanic corrosion. Correct Answer True

As galvanic corrosion is a bi-metallic corrosion, relatively less corrosion-resistant metal preferentially acts as anode and relatively high corrosion-resistant metal preferentially acts as a cathode. This increases attack on the less corrosion-resistant metal (anode) and decreases on high corrosion-resistant metal (cathode).

In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity I: Before 4 years, the population of the village is 8000. If the population of the village is increased by 5% in the first year, decreased by 8% in the second year, again decreased by 5% in the third year and increased by some per cent in forth year. The difference between the population of the village before 4 years and after 4 years is 75.76. Find the percentage by which the population increased in the forth year. Quantity II: 9%
