Answered by AadityaParashar

Answer:

48.235

Step-by-step explanation:

Total Marks for first group = 50 * 40

Total Marks for second group = 60 * 35

Total Marks for combined group = 2000 + 2100 = 4100

Total Students for combined group = 50 + 35 = 85

Mean Marks for combined group = 4100 / 85 = 48.235
