Answer 2

Hence, the value of missing numbers (upper box) = 7 and 9 and

the value of missing numbers (lower box) = 12 and 7.

Step-by-step explanation:

To find, the missing numbers of all boxes = ?

7   + 9 = 16

+    +

19 - 7 = 12

⇅     ⇅

26    16

Check:

7 + 9 = 16

7 + 19 = 26

9 + 7 = 16 and

19 - 7 = 12

All values satisfied.

The value of missing numbers (upper box) = 7 and 9 and

The value of missing numbers (lower box) = 12 and 7.

Hence, the value of missing numbers (upper box) = 7 and 9 and

the value of missing numbers (lower box) = 12 and 7.
