SOLUTION
If 2x(5n) = t, what is the value of t?
(1) x= n+ 3 --> 2(n+3)(5n) = t. Not sufficient.
(2) 2x = 32 --> x=16. Not sufficient.
(1)+(2) From (2) we have that x = 16, thus from (1): n = x - 3 = 13. We can find t. Sufficient.
Answer: C.

From question stimulus:10nx=t
From S1:x=n+3.Insufficient as we want absolute value of both n and x.
From S2:x=16.Insufficient as it doesn't provide value of n
Combining the 2 statements,we get x=16 and n=13.Hence,we can find out t.
