Question

84:23::89:27::64:42::36:?​

Answer 1

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

Answer 2

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
