Question

The mean of ten numbers is 50. What is the sum of the ten numbers?

Answer 1

Step-by-step explanation:

Let the sum of the ten numbers be a and the new number added be b

Mean = a/10

a/10 = 50

=> a = 500 ------(1)

When new number is added

Mean = 50

=> (a+b)/ 11 = 50

=> a + b = 550

=> 500 + b = 550

=> b = 550 - 500

=> b = 50

The number that is added is 50
