Among Tea and Coffee, which crop witnessed higher export (in terms of volume) for the period 1989-1992?
Shortcut: Except 1990, we can see that for each of the year between 1989-1992, coffee has higher exports as compared to tea. And for 1990, the higher production of coffee is compensated by much higher production of tea in other months. Conventional: We can calculate the exact export data for each year and then compare the two. We will still get the same answer
