Answer:
Deepak
Step-by-step explanation:
To find the mean of a given set of numbers, we must add all the values and divide by the number of numbers. For Arun, we get:
70 + 76 + 78 + 50 + 60 + 81
This is equal to
415
Now, we divide by 6 to get
69 1/6
We do the same for Deepak to get:
90 + 70 + 60 + 75 + 80 + 85
To get
460
We divide by 6 to get
76 4/6 = 76 2/3
We see that Deepak has the higher score and his higher by 7.5
