In the following question, a matrix of certain characters is given. These characters follow a certain trend, row-wise or column-wise. Find out this trend and choose the missing character accordingly.
28 60 48
5 6 7
17 39 27
7 ? 16

Answer: D. 27

The number in the second column is three times the difference between the numbers in the third and first columns.
So, missing number = 3 x ( 16 - 7 ) = 3 x 9 = 27.
