weighted average problem

avg = \(\frac{(20000*5 + 22000*4 + 25000*8 + 30000*3)}{20}\) = 23900

ans C

Remove zeros and add them later

Av=20*5 +22*4 +8*25 +30*3 /20
=23.9 multiply by 1000 =23900

Hi,
Simply assume that all get 20,000 then the average would have been 20,000.
Now 4 people get 2000 more than average, 8 people get 5000 more than average, 3 people get 10000 more than average
the total would be (4*2000)+(8*5000)+(3*10000)=78000
And this additional 78000 would be divided equally among 20 people

newavg= 20,000+(78000/20)
=20,000+3900
=23,900

Hence Option C

OFFICIAL GMAT EXPLANATION

From the table, there are 5 employees each with a salary of $20,000, 4 employees each with a salary of $22,000, and so on. The average (arithmetic mean) for all 20 employees is then:

5(20,000) + 4(22,000) +8(25,000) + 3(30,000)
______________________________________
20

= 100,000 + 88,000 + 200,000 + 90,000
____________________________________
20

= 478,000
________
20

= 23,900
