Maths IQ Puzzles With Answers

The answer is 40.
We have shared the detailed solution below.
Starting with the bottom row:
=> 4 + 20 / 2 = 12
=> 60 + 12 / 2 = 36
Similarly, we will apply the logic to figure out the X.
=> 20 + 60 / 2 = 40
Now, we will verify if we have the right value of X.
=> 12 + 40 / 2 = 26
=> 40 + 36 / 2 = 38
Hence, the missing number is 40.
