EXPLANATION.
Question = 1.
Batsman scored the following number of runs.
35, 30, 45, 65, 39, 20.
As we know that,
Mean = Sum of all the observation/the number of observation.
Sum of all observation = 35 + 30 + 45 + 65 + 39 + 20 = 234.
Number of observation = 6.
⇒ Mean = 234/6.
⇒ Mean = 39.
Option [A] is correct answer.
Question = 2.
Mean number of 10, 20, 30 and 40.
As we know that,
Mean = Sum of all the observation/the number of observation.
Sum of observation = 10 + 20 + 30 + 40 = 100.
Number of observation = 4.
⇒ Mean = 100/4.
⇒ Mean = 25.
