Will the answer be D? Statement 1: 3^(4n-1) = 27 so 3^(4n-1) = 3^3; (4n-1)=3; n=1 so m = 1 from main question which gives m/n = 1. Statement 2: m=3^(3n+1); also m = 3^(n-1); 3^(3n+1) = 3^(n-1); (3n+1)=(n-1); n = -1; m= 1/9; m/n = 1/9. Please correct if I am wrong.

Statement 1: Solve to find the value of n Put this value of n in equation for m to solve for m So now you the value for both m and m. Hence, you can find the value of m/n

Statement 2: Equate the values of m from equation provided in stem and statement 2 to solve for n. Put this value of n in equation of m from stem to solve for m. Hence, now you have values for both m and n.

Both the statements are sufficient on their own to find the value of m/n Hence, D

i am getting n = +1 from statement 1 and n = -1 from statement 2.. i am sure answer is D i dont know where i am doing mistake

The answer must be A because statement 1 tells that n is positive where as the value of m is totally dependent on n (either negative or positive). So we know that n is +1 and we can find the answer of m/n

both the statements yielding different values of m/n

Yes, you are right. Edited the second statement. Thank you.
