Question

The average of 10 numbers is 36 whenone more number is added to them,the new average is 38. which is thenumbers added? ​

Answer 1

Answer:

58

Step-by-step explanation:

Mean = sum of observations / number of observations

Given,

36 = sum of observations / 10

Sum of observations = 360

Now one more number is added

so,

38 = sum of observations /11

sum of observations = 418

So the number added = 418 - 360 =58
