Question

mode 62 median62.5 find mean using mean- mode= 3( mean - median

Answer 1

The formula is
mode +2mean=3median
so 2mean=3median - mode
2 mean= 2×62.5 - 62 = 125-62=63
so mean=63÷2=31.5

Answer 2

2 mean=3median-mode,

2 mean=3×62.5-62,

2 mean=187.5-62,

2 mean=125.5,

then

mean=125.5/2,

mean=62.75
