Question : Directions: Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number.
16 : 49 :: 18 : 55 :: 36 : ?
Option 1: 119
Option 2: 109
Option 3: 107
Option 4: 113
Correct Answer: 109
Solution :
Given:
16 : 49 :: 18 : 55 :: 36 : ?
Like, 16 : 49→(16 × 3) + 1 = 48 + 1 = 49
18 : 55→(18 × 3) + 1 = 54 + 1 = 55
Similarly, for 36 : ?→(36 × 3) + 1 = 108 + 1 = 109
So, 109 is related to 36. Hence, the second option is correct.
