Correct Answer – Option 3 : 7
CONCEPT:
Relationship between Mean, Median and mode:
Mode = 3 Median – 2 Mean
CALCULATION:
Given: In a frequency distribution, the mean and median are 10 and 9 respectively
As we know that, Mode = 3 Median – 2 Mean
⇒ Mode = (3 × 9) – (2 × 10) = 7
Hence, option C is the correct answer.
