Select the option in which the number does NOT share the same relationship as that shared by the given pairs of numbers.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 - Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
32 : 65 and 35 : 71
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 30:59.
32 : 65 → 32 × 2 + 1 = 65
35 : 71 → 35 × 2 + 1 = 71
Similarly, 30 : 59 → 30 × 2 + 1 = 61 ≠ 59
