84:23::89:27::64:42::36:?
Answers
Answer:
The missing number = 81
Step-by-step explanation:
This is a mathematical reasoning problem.
We see that,
84 = 8 × 4 = 32 = 23
89 = 8 × 9 = 72 = 27
64 = 6 × 4 = 24 = 42
The reasoning is such that the digits in the product of the digits of the numbers be interchanged.
Then,
36 = 3 × 6 = 18 = 81
Therefore the missing number is 81 and the complete proportion is
84 : 23 :: 89 : 27 :: 64 : 42 :: 36 : 81
