Question : Directions: Select the option that is related to the third term in the same way as the second term is related to the first term and the sixth term is related to the fifth term.
25 : 18 :: 37 : ? :: 49 : 36
Option 1: 29
Option 2: 32
Option 3: 30
Option 4: 27
Correct Answer: 27
Solution :
Given:
25 : 18 :: 37 : ? :: 49 : 36
Add the sum of the digits of the first number in itself and then subtract the sum from the first number to obtain the second number.
Here, 25 : 18→25 – (2 + 5) = 25 – 7 = 18
And, 49 : 36→49 – (4 + 9) = 49 – 13 = 36
Similarly, follow the same pattern for 37 –
37 : ?→37 – (3 + 7) = 37 – 10 = 27
So, 27 is related to 37 in the same way as other pairs are related. Hence, the fourth option is correct.
