Using the empirical relationship: Mode = 3 Median − 2 Mean
Mode = 3 × 40 − 2 × 43 = 120 − 86 = 34
The correct option is A) 34.
The empirical relationship between the three measures of central tendency is:
Mode = 3 Median − 2 Mean
This formula is stated in Chapter 13. Always substitute Median first, then Mean. Here: 3(40) − 2(43) = 120 − 86 = 34. This is a standard 1-mark application question in board exams.
