Question

If the average of five numbers is -20
and the sum of three of the number is
32 then what is average of the
other two number.​

Answer 1

Answer:

-132

Step-by-step explanation:

Average of first five numbers x1+x2+x3+x4+x5/5=-20

x1+x2+x3+x4+x5=-20×5

×1+×2+×3+×4+×5=-100

sum of three numbers is 32

×1+×2+×3=32

Then, we get

×1+×2+×3+×4+×5=-100

32+×4+×5=-100

×4+×5=-100-32

×4+×5=-132

Answer 2

Average of other two numbers is 34.

Step-by-step explanation:

Average of a given data is defined as the ratio of sum of observation to the total number of observation.

$\text{Average}=\frac{\text{Sum of observation}}{\text{Total number of observations}}$

From the given directions,

$20=\frac{\text{Sum of observation}}{5}\\\\\text{Sum of observation}=100$

Let the last two digits are x and y.

It has been given that  sum of three of the number is  32. Thus, we have

$32+x+y=100\\\\x+y=100-32\\\\x+y=68\\\\\frac{x+y}{2}=34$

Hence, average of other two numbers is 34.
