Hey mate, here is your answer-:)

___________________________

$\: \: \: \: \: Mode = 50.5 \\ Median = 45.5 \\ \\ \\ \: \: \: \: \: \: \: 3Median = Mode + 2Mean \\ \: \: \: \: \: \: \: \: 3 \times 45.5 = 50.5 + 2Mean \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: 136.5 = 50.5 + 2Mean \\ 136.5 - 50.5 = 2Mean \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 86 = 2Mean \\ \: \: \: \: \: \: \: \: \: \: \: \: Mean = \frac{86}{2} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: Mean = 43$
