Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the one that is different. (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.) 17 : 82 31 : 158 19 : 92 47 : 232
31 : 158
The following reasoning is as follows:
Reasoning: First number × 5 - 3 = Second number
Now,
For 17 : 82,
⇒ 17 × 5 - 3
⇒ 85 - 3 = 82
For 31 : 158 ,
⇒ 31× 5 + 3
⇒ 155 + 3 = 158
For 19 : 92 ,
⇒ 19× 5 - 3
⇒ 95 - 3 = 92
For 47 : 232 ,
⇒ 47× 5 - 3
⇒ 235 - 3 = 232
Here, option 1 i.e. '31 : 158' is different from the given pairs.
Thus, the correct answer is "Option 1".
