IMO, C
STATEMENT 1 : 3 ^(x+1) = 243
This means :
3 ^(x+1) = 3^5
Hence, X+1 = 5 , X=4.
This statement does not say anything about y. Insufficient.
STATEMENT 2 : 3^(y–1)=27
This means:
3^(y–1) = 3^3
Hence, Y-1 = 3, Y=4.
This statement does not say anything about x. Insufficient.
STATEMENT 1 AND 2 TOGETHER,
3^(X-Y) (Question stem)
= 3^(4-4)
= 3^0
= 1
Dear mentors and fellow members of the club, please let me know if I can improve my solution. Thanks
