Question

The mean of ten numbers is 56 find the sum of the numbers

Answer 1

See a solution process below: Explanation: First, let's call the two numbers: n and m. Now, we can write: Equation 1) n+m=56. Equation 2) ... n=56−m. Step 2) Substitute 56−m for n in the second equation and solve for m

Answer 2

lets assume 10 numbers are x1 , x2 , .....x10

now mean of 10 numbers are = sum of 10 numbers / 10 = 56

(x1 +x2+ ......+x10) / 10 = 56

(x1 +x2+ ......+x10)= 56× 10 = 560
