Question 52
The bar chart given below shows the total exports (in = 1000 crores) of a country for 7 consecutive years Y1, Y2, Y3, Y4, Y5, Y6 and Y7.
What is the average exports from years Y1 to Y7?
Solution
Exports for 7 years(in 1000 crores) are:
Y1 = 500
Y2 = 2750
Y3 = 1000
Y4 = 1200
Y5 = 1100
Y6 = 900
Y7 = 1300
Average export(in 1000 crore) = $$\dfrac{500+2750+1000+1200+1100+900+1300}{7} = \dfrac{6750}{7} = 964.28$$
