There is a typo in this question or the options as none of the options are the correct answer. Since option C is given correct, it seems the option C should have been 88L 500ml.

(B)

2 star + moon = 1960

4 star + moon = 2780

Now, 2 star + 1960 = 2780

          2 star = 820

          1 star = 410

Also, 2 star + moon = 1960

         820+moon = 1960

          moon = 1960-820 = 1140

Therefore, 3 star + 3 moon = 1230+3420=4650
