Option 1: 18 : 306
Option 2: 23 : 552
Option 3: 13 : 182
Option 4: 25 : 650
Correct Answer: 18 : 306
Solution :
Let's check each option –
First option:
18 : 306→18
2
+ 18 = 342
Second option:
23 : 552→23
2
+ 23 = 552
Third option:
13 : 182→13
2
+ 13 = 182
Fourth option:
25 : 650→25
2
+ 25 = 650
So, the first option is different from the other three options as here the resultant is 342 instead of 306. Hence, the first option is correct.
