The average of eight numbers is 80. Find the least number if it is $$\frac{1}{16}$$ of the sum of the numbers.​

Correct option is A

Given:
Average of 8 numbers = 80
The least number is $$\frac{1}{16}$$​ of the total sum
Formula Used:
Sum of observations = Average × Number of observations
Solution:
Total sum of 8 numbers = 8 × 80 = 640
Least number = $$\frac 1{16}$$​ × 640 = 40
