Question

if median is 75 and mode is 60 find mean

Answer 1

mode = 3median -2mean
therefore mean =(3median -mode)/2
implies mean = (3(75)-60)/2
=(225-60)/2
=77.5

Answer 2

since
mean - mode =3(mean - median)
mean - mode = 3mean-3median
mean = (3median-mode)/2
= {(3×75)-60}/2
= {225-60}/2
= 165/2
= 82.5
......which is required answer
