The second number in the given number pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) are followed in all the number pairs, EXCEPT one. Find that odd number pair.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (10, 100).
Logic : (Square of First number - 2) = Second number
As,
Option 1: (8, 62) ⇒ (8)2 - 2 = 64 - 2 = 62
Option 2: (10, 100) ⇒ (10)2 - 2 = 100 - 2 = 98 (not 100)
Option 3: (14, 194) ⇒ (14)2 - 2 = 196 - 2 = 194
Option 4: (12, 142) ⇒ (12)2 - 2 = 144 - 2 = 142
So, (10, 100) is different one.
Hence, the correct answer is (10, 100).
