Given:
Mean of 2x-10 = 40
To find:
The mean of 3x+5
Calculation:
Mean of n numbers is given by the formula
Mean = Sum of observations/Number of observation
Case 1:
Mean of 2x-10 = 40
=> 2x-10/1 = 40
=> 2x-10 = 40
=> 2x = 50
=> x = 25
Case 2:
Mean of 3x+5 = 3x+5/1
=> Mean = 3x+5
=> Mean = 3(25)+5 [x=25]
=> Mean = 80
The mean of 3x+5 is 80
