Question : Directions: Select the option in which the numbers do 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 their 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
35 : 71
Option 1: 21 : 43
Option 2: 46 : 93
Option 3: 17 : 35
Option 4: 30 : 59

Correct Answer: 30 : 59
Solution :
Given:
(32 : 65); (35 : 71)
Multiply the first number by 2 and then add 1 to obtain the second number –
(32 : 65)→(32 × 2) + 1 = 64 + 1 = 65
(35 : 71)→(35 × 2) + 1 = 70 + 1 = 71
Let's check the options –
First option:
(21 : 43)→(21 × 2) + 1 = 42 + 1 = 43
Second option:
(46 : 93)→(46 × 2) + 1 = 92 + 1 = 93
Third option:
(17 : 35)→(17 × 2) + 1 = 34 + 1 = 35
Fourth option:
(30 : 59)→(30 × 2) + 1 = 60 + 1 = 61 ≠ 59
So, only the fourth option doesn't follow the same pattern as followed by the given set of numbers. Hence, the fourth option is correct.
