Question

find the arithmetic mean of the following number, 3000, 3500,3600,3900, 4000, 4500,5000,6000,7000, 8000

Answer 1

Answer:

Total number of workers =30

Sum of slaries of all the workers =(8×3000)+(7×4000)+(4×5000)+(4×6000)+(3×7000)+(3×8000)+9000

=24000+28000+20000+24000+21000+24000+9000=15000

Mean of monthly salary =

30

150000

=5000

Hence the mean of monthly salary is Rs.5000.

Answer 2

The Arithmetic mean of the given numbers is

$4850$

Explanation:

Sum of given numbers =

$3000 + 3500 + 3600 + 3900 + 4000 + 4500 + 5000 + 6000 + 7000 + 8000$

$= 48500$

Arithmetic mean of the given number

$= \frac{48500}{10} \\\\= 4850$
