Correct Answer: 51


Solution : Multiply row one with row two and subtract the resultant by row three, to get the required missing number in row four –

In column one : 9 × 6 – 4 = 54 – 4 = 50
In column three: 7 × 8 – 3 = 56 – 3 = 53
In column two: 8 × 7 – 5 = 56 – 5 = 51

So, the required missing number in the matrix is 51. Hence, the first option is correct.
