Solution :
Median - Mean = ?
Mode-Median = 24 (Given)
Mode = 24+Median — (1)
Mode-Median = 24 (Given)
Mode = 24+Median — (1)
We know,
3 Median = 2 Mean + Mode
3 Median = 2Mean + 24 + Median
[Using eq (1)]
3Median-Median-2Mean = 24
2Median - 2Mean = 24
2(Median-Mean)=24
2Median - 2Mean = 24
2(Median-Mean)=24
Median - Mean = 24/2
Median - Mean = 12
Median - Mean = 12
Hence, b) would be the correct option.
