The given problem is related to finding the mean of a set of values. We are given that the mean of 50 values is 15. We are also told that two values, 18 and 12, are eliminated from the set. We need to calculate the new mean after removing these two values.

To solve this problem, we can follow these steps:

1. Find the sum of the original set of values:
- We are given that the mean of the original set of values is 15.
- The mean is calculated by dividing the sum of the values by the total number of values.
- Let's assume the sum of the original set of values is S.

2. Find the sum of the remaining set of values:
- Since two values (18 and 12) are eliminated, we need to find the sum of the remaining 48 values.
- Let's assume the sum of the remaining set of values is S'.

3. Find the new mean:
- The new mean can be calculated by dividing the sum of the remaining values (S') by the total number of remaining values.
- Since we eliminated two values, there are now 48 remaining values.

4. Substitute the given information and solve for the new mean:
- We are given that the mean of the original set of values is 15, so we can write the equation as:
S / 50 = 15
- We need to find the sum of the remaining values, so we can write the equation as:
S' / 48 = ?
- We can solve for S' by multiplying both sides of the equation by 48:
S' = 48 * 15

5. Calculate the new mean:
- Now that we have the sum of the remaining values, S', we can calculate the new mean by dividing S' by 48.

In summary, to find the mean after eliminating two values, we need to find the sum of the remaining values and divide it by the total number of remaining values.

Mean=15

sum of all terms= 15×50=750

two terms eliminated

sum of new terms=750-18-15=717
new mean =717/48
=14.93
