Select the option in which the numbers share the same relationship as that shared by the given pair of numbers.
12 : 20
Answer & explanation
Correct answer: option 1
12 : 20
The logic followed here is :
12 = 32 + 3 = 9 + 3 = 12
20 = 42 + 4 = 16 + 4 = 20
Similarly 30 : 42
30 = 52 + 5 = 25 + 5 = 30
42 = 62 + 6 = 36 + 6 = 42
