Which of the following number will replace the question mark (?) in the given figure matrix, if the same rule among the numbers is followed either row-wise or column-wise?
The second row is 5 times the first row, as $$3 \times 5 = 15$$ and $$7 \times 5 = 35$$, and the third row is 9 times the first row, as $$3 \times 9 = 27$$, $$8 \times 9 = 72$$ and $$7 \times 9 = 63$$. So the missing number is $$8 \times 5 = 40$$.
