The average of eight numbers is 20. The average of five of these numbers is 12. The average of the remaining three numbers is

Correct option is A

Given:

Average of 8 numbers = 20

Average of five of these numbers = 12

Formula Used:

Average =$$\frac{Sum\ of \ observations}{Number\ of \ observations}$$​​

Solution:

Total of 8 numbers  = 8 $$\times$$​ 20  = 160

Total of 5 numbers = 5 $$\times$$​12 = 60

Total of remaining numbers = 160 - 60 = 100

Average of remaining numbers $$= \frac{100}{3} =33\frac{1}{3}\ or\ 33.333$$​​
