Study the following graph carefully and answer the questions that follow. Consumption of two metals in the given years by a company (in '000 tones)
Q42. In how many years, the consumption of metal A was less than the average consumption of metal B in the given years?
Average consumption of metal B = 25+20+19+26+26+356=151.006
= 25.2 thousand tons
It is obvious from the graph that the consumption of metal A was less than the average in the years 1988, 1989, 1990, 1992, and 1993.
