37

Answer 1

○=> Correct option :

`\color{plum}\bold{(b) \: 30}`

○=> Steps to derive correct option :

▪︎Mode is the most frequently occurring element in a given data set.

The given data set :

`=\tt 30,28,30,45,40,37,35`

Let us first arrange these numbers in ascending order :

`=\tt 28,30,30,35,37,40,45`

As we can clearly observe, the number 30 occurs the most frequently.

Thus, the mode of this data set = 30

Therefore, the correct option is (b) 30

Answer 2

30

Explanation:

mode is the number that occurs most of the time

since 30 appears twice in the data set

while the other numbers only appear once,

30 is the mode
