Given that the mean of five numbers is 28. If one of them is excluded, the mean gets reduced by 5. Determine the excluded number. |
47 45 48 46 |
48 |
The mean of five numbers = 28 After excluding one number the mean reduced by 5. So the excluded number = 28 + 5 × remaining numbers So the excluded number = 28 + 5 × 4 = 48 |
