What was the average production of cups of espresso per machine for machines A, B, C, and D last week?

1) Machine A and D produced a total of 503 cups of espresso last week.
2) Machine B and E produced a total of 405 cups of espresso last week.

OA E
Even both statements can't help as we have no information about machine C.
