a% of b = a/100*b or, ab /100. So, basically the question is asking whether we can derive the value of ab/100 from the given information.
Statement 1 :
200% of a% of b = 360
or, 2a% of b =360
or, 2a/100* b = 360
or, 2ab/100 =360
So, ab/100 = 180. SUFFICIENT
Statement 2 :
b% of a = 180
or, b/100* a = 180
So, ab/100 = 180. SUFFICIENT
Answer: D

1) 200% of a% of b=360
i.e 2a% X b =360
2ab/100=360
ab/100=180
suff
2) b% of a = 180
as we know a% of b = b% of A
sufficient
IMO D
