Total residents in Town T=35,000
40% of T earn at least $50,000 per year. Implying 0.4*35,000 = 14,000 residents earn at least $50,000 per annum
We are to find what proportion of those residents of T earning at least $50,000 that work for company X
statement 1 states 5,600 residents of T work for X.
This is insufficient since we have no information about how many out of the 5,600 earn at least $50,000
statement 2 states that X has 1,800 who earn at least $50,000 per year.
So we know that 1800 employees of X earn at least $50,000. Are all these employees from town T? The question did not state that all the employees of X work for Town T, hence we are still not able to determine the total number out of 1,800 earning at least $50,000 who are from Town T. So in my view, statement 2 is still insufficient. The question needs to be explicit. We are not even sure if company X is located within Town T.
1+2 still not sufficient. We only know that 5,600 employees of X are from Town T. That does not in anyway imply that the total number of employees for X is 5,600. We also know that 1,800 employees of X earn at least $50,000. We cannot be sure if all these employees are residents of town T. 1+2 taken together is still not sufficient in my view.
Answer has to be E imo.
