If the median of Set A above is one less than the mode of Set A, which of the following is a possible value of x ?

A. 3
B. 5
C. 6
D. 7
E. 9


avg of set = 27+x/6
now mode of set is most repeated term of set
here options can be 3,5,7 only
upon checking with all these options only at 7 we get median = ~ 5.6 ; 6 which is 1 less than mode 7
IMO D
