Calculate the number of years during 2005 to 2013 for atleast one of thetwo rice when income and expenditure did not follow the same trend (i.e both incomeand expenditure did not increase or decrease simultaneously compared to theprevious year)?
Explanation:
We have to count the years in which at least one of the rice's income and expenditure shows an opposite trend. 2005: Parmal rice has an opposite trend. 2006: None of the rice has opposite trends. 2007: Basmati rice has an opposite trend. 2008: Basmati rice has an opposite trend. 2009: Both the rice show an opposite trend. 2010: Both the rice show an opposite trend. 2011: Both the rice show an opposite trend. 2012: Basmati rice has an opposite trend. 2013: Basmati rice has an opposite trend. Thus, all the years except 2008 have at least one rice showing an opposite trend in income and expenditure. Thus, there are a total of 8 years. Hence, the answer is option C.
