increasing rate of farmers < increasing rate of population....(condition 1)
according to Chris Lele:
the population has increased from 10000 to 50000 (400 % increase)
farmers has increased from 1000 to 2000 (100% increase)
farmers : population = (2000 / 50000 ) * 100 % = 4 % [ proportion ]
if population was increased to 20000, then it would be 100% increase of population
farmers : population = (2000 / 20000) * 100 % = 10 % [proportion ]
if condition 1 remains intact, proportion decreases; although answer E says proportion increases.

You got it, Afif! According to the condition, the proportion of farmers *decreases*. The question asks us to find an answer that *contradicts* this, that is, says the opposite of this. So that's what choice E says. It contradicts the condition we're given, saying the opposite. That's why it's the right answer :)
