Question

The mean of two numbers is 16. One of them is 10. Find the other number​

Answer 1

Answer:

the other no. is 6 because the means is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. 

Answer 2

Step-by-step explanation:

Suppose that two numbers are x and y

x+y =16→(1)

x-y=10→(2)

Now, sub (2) from (1)

x+y=16

x-y=10

From x + y - ( x-y) ,

we get ,x + y-x+y

= 2y

From 16- 10

We get, 6

So, the answer after sub of equation 1 and 2 is,

2y =6

y=6/2

y=3

Now , put y=3 in equation (1)

x+y=16

x+3=16

x=16–3

x=13

Thus, we get the two numbers x and y,

13,3

13+3=16

13–3=10

Hope this helps you.
