19. We may also point out that application of a flat rate will lead to anomalous results. This may be demonstrated with further reference to the above illustration. In regard to the sale transaction in 1987, where the price was Rs 10 per square metre, if the annual increase to be applied is a flat rate of 10%, the increase will be Rs 1 per annum during each of the five years 1988, 1989, 1990, 1991 and 1992. If the price increase is to be determined with reference to sale transaction of the year 1989 when the price was Rs 12 per square metre, the flat rate increase will be Rs 1.20 per annum, for the years 1990, 1991 and 1992. If the price increase is determined with reference to a sale transaction of the year 1990 when the price was Rs 13 per square metre, then the flat rate increase will be Rs 1.30 per annum for the years 1991 and 1992. It will thus be seen that even if the percentage of increase is constant, the application of a flat rate leads to different amounts being added depending upon the market value in the base year. On the other hand, the cumulative rate method will lead to consistency and more realistic results. Whether the base price is Rs 10 or Rs 12.10 or Rs 13.31, the increase will lead to the same result.
