Correct Answer: Option C
Explanation

x = no. of ppl that like none.

no. of ppl that like both Traditional and Modern music, which is equal to 3x

Modern Music = 60 - 3x

Traditional Music = 50 - 3x

60-3x + 50 - 3x + 3x + x  = 94
110 - 3x + x = 94
-2x = 94 - 110

=>-2x = -16,

this x = 8.

Members that like only one music:
= 60 - 3x + 50 - 3x
= 60 - 3[8] + 50 - 3[8]
= 60 - 24 + 50 - 24
= 36 + 26 = 62

Members that like only one type of music = 62
