We can say that the number of cars sold in location A last month = x and the cars in location B = y.
So current sales in A = 2x and current sales in B = 2/3y ; Total Sales = 2x + 2/3y
Answer is C, as we need both to know that S = 2(176) + 2/3(80) = 352 + 53 (can't sell 0.333 of a car) = 405

Given data in question stem
Cars sold / salesperson Last month This month
Location A ------------- 11 --------- 22
Location B ------------- 18 --------- 12
Statement 1 : Location A sold 176 cars last month.
With the above information, we can find out how many employees work at Location A
using Number of cars/Cars sold per salesman last month
and with that, we can calculate the cars sold by the dealership at Location A.
Since we do not have any information about Location B,
we cannot find out the total cars sold by the dealership.
Statement 2 : Location B sold 80 cars last month.
With the above information, we can find out how many employees work at Location B
using Number of cars/Cars sold per salesman last month
and with that, we can calculate the cars sold by the dealership at Location B.
Since we do not have any information about Location A,
we cannot find out the total cars sold by the dealership.
Combining the two options we can arrive at a unique solution for the total number of cars sold(Option C)
