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.

4C 2B 3A
28A ? 45B
7C 5A 15B

A. 10C
B. 12C
C. 13C
D. 7C
Answer: A . 10C


In each row, out of the letters A, B and C, each of these must appear once. In each column, the product of the first and third numbers is equal to the second number.
So, the missing number will be (2 x 5) i.e. 10 and the letter will be C.
Thus, the answer is 10C.
