Question

If mean of 20 observations is 25 and median is 24.5 then the mode is

Answer 1

mean - mode = 3 ( mean - median)

➡ given mean = 25 ; median = 24.5

➡ 25- mode = 3(25 - 24.5)

➡ 25 - mode = 3(0.5)

➡ 25 - mode = 1.5

➡ - mode = 1.5 - 2.5

✒ mode = 1

Answer 2

mode=3median-2mean
. =3x24.5-2x25
. = 73.5-50
. =23.5

so, mode=23.5
