Am of 10 no.is 15 .if 2 no.20&18are excluded,then mean of remaining numbers is?

Question

Answer

Calculation of Mean of Remaining Numbers

Given:

Step 1: Calculate the Sum of Remaining Numbers

First, we need to exclude the numbers 20 and 18 from the initial set. Therefore, the remaining numbers are 10 and 15.

Sum of remaining numbers = 10 + 15 = 25

Step 2: Determine the Count of Remaining Numbers

Since we have excluded two numbers, the count of remaining numbers is 2.

Step 3: Calculate the Mean of Remaining Numbers

The mean is calculated by dividing the sum of numbers by the count of numbers.

Mean = Sum of numbers / Count of numbers = 25 / 2 = 12.5

Conclusion

The mean of the remaining numbers (10, 15) after excluding 20 and 18 is 12.5.
