If A is directly proportional to the square of B, B is inversely prop...
As per the given information in the question
C is directly proportional to D
D increases by 200% so it becomes 3 times
So, C becomes 3 times.
B is directly proportional (1/C2) = 1/9
B becomes (1/9) times
A is directly proportional B2 = (1/9)2 = (1/81) times
A becomes (1/81) times.
