Direction: Choose the correct options from the alternative 52 :27 :: 62 : ?
64
This is a number-analogy question where the two digits of the first number are combined to produce the second number.
Take the first pair, 52. Separate its digits: 5 and 2.
Subtract the second digit from the first: \(5 - 2 = 3\).
Now cube this result: \(3^{3} = 27\), which is exactly the second term of the first pair.
So the rule is: (first digit \(-\) second digit) cubed \(=\) the answer.
Apply the rule to 62. Digits are 6 and 2, so \(6 - 2 = 4\).
Cube it: \(4^{3} = 64\).
This matches the highlighted option, while 72, 26 and 125 do not follow the same rule. Hence the answer is 64.
