Correct Answer - Option 3 : 8

Given

Mean = 5

Median = 6

Formula used

Mode = 3Median − 2 Mean

Calculation

Mode = 3(6) - 2(5)

⇒ 18 - 10 = 8

 The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.

The median is the middle value when a data set is ordered from least to greatest.

The mode is the number that occurs most often in a data set.
