Posted by Abhay Pandey 6 years, 3 months ago

CBSE > Class 10 > Mathematics

1 answers

Yogita Ingle 6 years, 3 months ago

Mean = 20 and mode =11

Mean – Mode = 3 (Mean – Median)

20 - 11 = 3 (20 - median)

9 = 3 (20 - median)

20 - median = 9/3 = 3

20 - median = 3

median = 20 - 3

median = 17

20 - median = 9/3 = 3

20 - median = 3
