a
6.71
b
4.52
c
7.61
d
5.33
detailed solution
Correct option is C
We have,Mean =20+25+30+18+15+406=1486Median =20+252=452∴ Mode = 3 Median -2 Mean =1352−1483=1096Hence, mean deviation about mode is given by 20−1096+25−1096+30−1096+18−1096+15−1096+40−10966 M.D. =11+41+71+1+19+13136=27436=7.61Talk to our academic expert!
