GMATinsightSo lemme try to understand this. From the question stem we know that the estimated per capita income should lie between -
(LOWER limit for the estimate of the total income/HIGHER limit for the estimate of the population) and (HIGHER limit for the estimate of the total income/LOWER limit for the estimate of the population)
Since st1+st2 give us (LOWER limit for the estimate of the total income/LOWER limit for the estimate of the population) which lies somewhere in the middle we cant answer the question.
So even if the question instead was- was the per capita income for the region LOWER than $17,000? we would not be able to answer it right? Just confirming. Thanks

In a demographic study, the population and total income of a certain region were estimated from other data, and both estimates had lower and upper limits. At the time of the estimates, was the per capita income for the region greater than $16500?
(1) The lower limit for the estimate of the population was 330,000
(2) The lower limit for the estimate of the total income was $5,500,000,000
Question : Is Income / Total Population > $16,500?Hint: The question require
Either, the minimum value of per capita Income which can be calculated by Minimum Income and Maximum Population
Or, the Maximum value of per capita Income which can be calculated by Maximum Income and Minimum PopulationStatement 1: The lower limit for the estimate of the population was 330,000Neither can we calculate Minimum Per capita Income nor Maximum Per capita Income. Hence,
NOT SUFFICIENTStatement 2: The lower limit for the estimate of the total income was $5,500,000,000Neither can we calculate Minimum Per capita Income nor Maximum Per capita Income. Hence,
NOT SUFFICIENTCombining the Two statementsUsing the Lower limit of both Neither can we calculate Minimum Per capita Income nor Maximum Per capita Income. Hence,
NOT SUFFICIENTAnswer: option E
