Correct Answer: 9
Solution :
Given:
11 : 31 :: ? : 25 :: 14 : 40
Multiply the given number by 3 and then subtract 2 from the resultant number to obtain the missing number –
Like, 11 : 31→(11 × 3) – 2 = 33 – 2 = 31
And, 14 : 40→(14 × 3) – 2 = 42 – 2 = 40
Similarly, follow the same pattern for 25 –
⇒ (? × 3) – 2 = 25
⇒ (? × 3) = 25 + 2
⇒ ? = 27 ÷ 3
⇒ ? = 9
So, 9 is the missing number in the given set of numbers. Hence, the fourth option is correct.
