Question

arithmetic mean of two numbers is 5 if one number is 6 find tye other number​

Answer 1

Answer:

let the other number be x

So

x+6/2=5

x+6=10

x=4

which is the required ans

Answer 2

Given - Mean and one number

Find - Other number

Solution - Let the number be x.

Arithmetic mean = sum of values/number of values

Sum of values = 6 + x

Number of values = 2

Keep the values in formula to find the value of x

$5 = \frac{6 + x}{2}$

$5 \times 2 = 6 + x$

Performing multiplication to find the value of x

$10 = 6 + x$

$x = 10 - 6$

Performing subtraction to find the value of x

$x = 4$

Therefore, the other number is 4.
