The triplicate ratio of 2 : 3 is
A3 : 2
B4 : 9
C6 : 9
D8 : 27
Answer & Solution
Correct answer: D. 8 : 27
1. The triplicate ratio of a : b is a^3 : b^3.
2. 2^3 = 8 and 3^3 = 27.
3. So the triplicate ratio of 2 : 3 is 8 : 27.
4. Option D is the DUPLICATE ratio (squared, not cubed) so it is the trap.
