Answer 1

Answer 2

Average of ten numbers = (sum of 10 numbers)/10

15 = (sum of 10 numbers)/10

15*10 = sum of 10 numbers

150 =sum  of 10 numbers  

 

Later on, one number was written wrong as 26,  

So, Now,

correct sum of numbers is  = 150-26+36

                                           = 150 + 10

                                           = 160

Now,

Correct Average = (sum of 10 numbers)/10

Correct average = 160/10

Correct average = 16/1

Correct Average = 16
