Question : Directions: In the following question, select the related number from the given alternatives. 20 : 30 :: ? : 72
Option 1: 56
Option 2: 59
Option 3: 68
Option 4: 61
Correct Answer: 56
Solution : Given: 20 : 30 :: ? : 72
In the given number pairs, add squares of consecutive numbers to itself. Like, 20 : 30→(4)2 + 4 = 16 + 4 = 20; (5)2 + 5 = 25 + 5 = 30 Similarly, follow the same pattern for (?) : 72→(7)2 + 7 = 49 + 7 = 56; (8)2 + 8 = 64 + 8 = 72
So, 56 is related to 72. Hence, the first option is correct.
