IF BOX 1 - BOX 2 = 9 , BOX3 - BOX4 = 14 , BOX1 + BOX3 =12 , BOX2 +BOX4 = 2 . FILL THE BOXES

Question

Answer 1

I tried hard. Surely there are some (-) figures.
Could you please check if the question is correct .

Answer 2

Its deterministic behavior, lets understand how -

What is Given

Box1 - Box2 = 9     ----------- 1
Box3 - Box4 = 14    ----------- 2
Box1 + Box3 = 12    ----------- 3
Box2 + Box4 = 2    ------------ 4

Now Eq1 + Eq4
Box1 + Box4 = 11 --- 5

Eq3 - Eq2
Box1 + Box4 = -2 ---6

Now we can see Box1 + Box4 in Eq5 and Eq6 are giving two different values which is not possible. Hence its deterministic behavior.

Comments

Thanks Salil. Its clear now. There is a conflict.
One of the solution to make it work is apply a suitable change to eq2 which can make the whole grid work.
