Answer (a):
The inflation distorts the ratio as their are number of things that inflate their prices differently. The prices of the rice is increasing by 1%, wheat prices are growing by 2% and salaries expenses are increasing by 5%. This means there is no consistant increase in all the commodity prices. And this issue becomes very prominent after 3 years.
