Question

Answer 1

Hey there!

Given Average of 6 numerals = 30

Average = Sum of observations / Number of observations.

Sum of observations = 30 * 6 = 180 .

If one number is excluded, number of observations left = 5 .

Given, Average of 5 observations = 29 .

Sum of 5 observation = 29 * 5 = 145.

Excluded number = Sum of total observations - Sum of observations excluding the 6th observation = 180 - 145 = 35 .

Therefore, Excluded number is 35
