For problems 31 to 33, refer to the following:
Real wage is a wage deflated by the current consumer price index. It gives information on
how much current wage compares to the wage of given base year period. Real wage is
obtained by dividing the nominal wage by the current Consumer Price Index (CPI) of a giver
month multiplied by 100. Table 1 below presents the real wage and nominal wage of non
agriculture workers in the Philippines as of December 2019 by region.
