What was the average production rate 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.

The OA is E.

Please, can any expert help me with this DS question? I don't understand it. Thanks.
