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) is/are followed in all the number pairs, except one. Find that odd number pair.
Option 1: 24 : 169
Option 2: 12 : 49
Option 3: 48 : 625
Option 4: 36 : 365
Correct Answer: 36 : 365
Solution :
Let's check the options –
First option:
24 : 169; 13
2
= 169 and (13 × 2) – 2 = 26 – 2 = 24
Second option:
12 : 49; 7
2
= 49 and (7 × 2) – 2 = 14 – 2 = 12
Third option:
48 : 625; 25
2
= 625 and (25 × 2) – 2 = 50 – 2 = 48
Fourth option:
36 : 365; 365 is not a perfect square.
So, only the fourth option is different from the other three options. Hence, the fourth option is correct.
