1. Find Mode when Mean=3 and Median=4
We have given Mean (bar X) = 3, Median(M) = 4, Mode(Z) = ?
Z = 3 M - 2 bar X
Z = 3 * 4 - 2 * 3
Z = 12 - 6
Z = 6
2. Find Median when Mean=5 and Mode=11
We have given Mean(bar X) = 5, Mode(Z) = 11, Median(M) = ?
Z = 3 M - 2 bar X
3 M = Z + 2 bar X
3 M = 11 + 2 * 5
3 M = 11 + 10
M = 21/3
M = 7
3. Find Mean when Median=7 and Mode=11
We have given Median(M) =7, Mode(Z) =11, Mean(bar X) =?
Z = 3 M - 2 bar X
2 bar X = 3 M - Z
2 bar X = 3 * 7 - 11
2 bar X = 21 - 11
bar X = 10 / 2
bar X = 5
