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.
72
24
6
96
16
12
108
?
18
Answer: A. 12
In the first row, 72 ÷ (24/2) = 72 ÷ 12 = 6. In the second row, 96 ÷ (16/2) = 96 ÷ 8 = 12. Let the missing number in the third row be y. Then, 108 ÷ (y/2) = 18 or y/2 = 108/18 = 6 or y = 12.
