Answer these questions based on the data given below: The figures below present annual growth rate, expressed as the % change relative to the previous year, in four sectors of the economy of the Republic of Reposia during the 9 year period from 1990 to 1998. Assume that the index of production for each of the four sectors is set at 100 in 1989 Further, the four sectors: manufacturing, mining and quarrying, electricity, and chemicals, respectively, constituted 20%, 15%, 10%, 15 % of total industrial production 1989.
It is known that the index of total industrial production in 1994 was 50 percent more that in 1989. Then, the percentage increase in production between 1989 and 1994 in sectors other than the four listed above is:
Since in 94 total production was 50% more than 89 , so total production = 150. Also we know that total production in given 4 sectors in 94  = 76.8. Hence other than the 4 sectors total production is 150 - 76.8 = 73.2 . Hence  the percentage increase in production between 1989 and 1994 in sectors other than the four listed above is: (73.2-40) / 40 is approx 87.5% . Hence option B.Â
