Question : Directions: 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.
Option 1: (2, 24)
Option 2: (4, 320)
Option 3: (5, 430)
Option 4: (3, 108)
Correct Answer: (5, 430)
Solution :
Let's check each option –
First option:
(2, 24)→(2)
3
+ (2)
4
= 8 + 16 = 24
Second option:
(4, 320)→(4)
3
+ (4)
4
= 64 + 256 = 320
Third option:
(5, 430)→(5)
3
+ (5)
4
= 125 + 625 = 750 ≠ 430
Fourth option:
(3, 108)→(3)
3
+ (3)
4
= 27 + 81 = 108
So, only the third option does not follow the pattern. Hence, the third option is correct.
