If the mode of the data set {a, a + 2, a + 4, a + 6, a + 6, a + 6, a + 8} is 26, find a.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 20.
Data set: a, a + 2, a + 4, a + 6, a + 6, a + 6, a + 8
Mode = 26 (The most frequent value = a + 6)
So, a + 6 = 26
⇒ a = 26 - 6 = 20
