Understanding from the table:
1. Minimum wage has increased by (5.85 - 2), i.e 192.5% over a period of 33 years.
2. Cost of standard basket of goods has increased by (202 - 47) i.e, 329.8% over a period of same 33 years.
Therefore it can be said that minimum wage has not increased in line with the inflation in the coy=untry, thus it has lead to decrease in purchasing power over a period of time.
This is also evident from the fact that in 1974 a person can buy 1.7 number of basket of goods while same person can only buy 1.16 number of basket of goods in 2007.
