Correct Answer: 6


Solution : Here, the sum of the numbers of the first and second rows is 16, so it should also be the same in the third row.

In the row one: 5 + 1 + 3 + 7 = 16
In the row two: 6 + 2 + 4 + 4 = 16
Similarly, in row three, all the numbers should add up to 16.
Therefore, 16 – (1 + 2 + 7) = 6

So, 6 is the required missing number. Hence, the fourth option is correct.
