Detailed Solution

Concept: Karl Pearson's Formula can be used to express the relationship between mean, median, and mode:

$M o d e = 3 M e d i a n - 2 M e a n$

Given: Median = 20, Mean = 18

$\Rightarrow M o d e = 3 M e d i a n - 2 M e a n$

$\Rightarrow 3 (20) - 2 (18)$

$\Rightarrow 60 - 36 = 24$

$∴ M o d e = 24$
