Question : Directions: In the following question, select the related number from the given alternatives. 20 : 30 :: 42 : ?
Option 1: 37
Option 2: 64
Option 3: 48
Option 4: 56
Correct Answer: 56
Solution : Given: 20 : 30 :: 42 : ?
Like, 20 : 30→(4)2 + 4 = 16 + 4 = 20 (5)2 + 5 = 25 + 5 = 30 Numbers 4 and 5 are the consecutive numbers. Similarly, for 42 : ?→(6)2 + 6 = 36 + 6 = 42 (7)2 + 7 = 49 + 7 = 56
So, 42 is related to 56. Hence, the fourth option is correct.
