Correct Answer: 14
Solution :
Given:
7 : ? :: 15 : 150 :: 18 : 234
Multiply the first number with a number that is five less than the first number to get the second number.
Like, 15 : 150→15 × (15 – 5) = 15 × 10 = 150
18 : 234→18 × (18 – 5) = 18 × 13 = 234
Similarly, follow the same pattern for 7 : ?→7 × (7 – 5) = 7 × 2 = 14
So, 14 is related to 7. Hence, the third option is correct.
