$mean \: 1 = \frac{total \: observation}{number \: of \: observation \: }$

$82 = \frac{(27 + x) + (89 +x) + (31 + x) + (107 + x) + (156 + x) }{5}$

$140 = 140 + x$

$x = 0$

$\: so \: mean \: 2 = \frac{(130 + x) + (126 + x ) + (68 + x) + (50 + x) + (10 + x)}{5}$

$= put \: \: x = 0$

$\frac{375}{5} = 75$
