Statement 1 --> 120 < \frac{3}{4}*4^x ==> 160 < 4^x ==> therefore, x > 3 ==> Insufficient. Statement 2 --> x = +5 or -5 ==> therefore, 3x is either +15 or -15 in both cases its less than 500 ==> Sufficient.

From statement 1 we get that x>=4 hence if x=4 the answer is yes, but if x10 the answer is NO. From statement 2 we get that x can be either -6 or 6, if x=6 then yes but if x = -6 then no. From both statements together we know that x = 6 so the answer is NO C

C is the answer to problems

Cheers J
