The mean of 12 numbers is 20 and the mean of another 8 numbers is 25 find the mean of the 20 numbers

AysviL [449]

Answer:

Step-by-step explanation:

mean is calculated as

mean = $\frac{sum}{count}$

Given the mean of 12 numbers is 20 , then

$\frac{sum}{12}$ = 20 ( multiply both sides by 12 )

sum = 240

Given the mean of 8 numbers is 25 , then

$\frac{sum}{8}$ = 25 ( multiply both sides by 8 )

sum = 200

Total sum of the 20 numbers = 240 + 200 = 440, then mean of 20 numbers is

mean = $\frac{440}{20}$ = 22
