Dear Student,

​Given:
 
12  8 10  7
14 16 13 15
 9 11  ? 13

​In the above rectangle, the sum of all the columns is 35:
​12 + 14 + 9 = 35
8 + 16 + 11 = 35
7 + 15 + 13 = 35
​So, 10 + 13 + ? = 35
​Thus, the number that will replace the question mark is 12, as 10 + 13 + 12 = 35.

​Hope this information will clear your doubts about this topic.
