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
