The sum of the deviations of a set of  values  measured from  and the sum of deviations of the values from 46 to 70. Find the values of  and the mean.

Explanation

To solve the problem step by step, we will use the information given about the sum of deviations from two different values (50 and 46) to find the number of values (n) and the mean (x̄).

### Step 1: Set Up the Equations
We know the following:
1. The sum of deviations from 50 is -10.
2. The sum of deviations from 46 is 70.

We can express these conditions mathematically:
