Set A = {3, 1, 7, 5, 11, x}

Plugging in option values for x

x = 3

=> mode = 3

=> median of {1,3,3,5,7,11} = 4 \(\neq\) mode - 1 INCORRECT

__________________________________________________________________________________________________

x = 5

=> mode = 5

=> median of {1,3,5,5,7,11} = 5 \(\neq\) mode - 1 INCORRECT

__________________________________________________________________________________________________

x = 6

=> mode can be 1, 3, 5, 6, 7, 11

=> median of {1,3,5,6,7,11} = 5.5 \(\neq\) mode - 1 INCORRECT

__________________________________________________________________________________________________

x = 7

=> mode is 7

=> median of {1,3,5,7,7,11} = 6 = mode - 1 CORRECT

__________________________________________________________________________________________________

x = 9

=> mode can be 1, 3, 5, 7, 9, 11

=> median of {1,3,5,7,9,11} = 6 \(\neq\) mode - 1 INCORRECT

Hence option D
