In a certain instruction system the different computation processes are written as follows: 

(i) A % B £ C means A is multiplied by the sum of B and C. 
(ii) A π B © C means A is subtracted from B and the resultant is divided by C. 
(iii) A ≠ B * C means A is added to the resultant when B is divided by C. 
(iv) A λ B @ C means the product of B and C is subtracted from A. 

In each of the question below, a set instruction sequence is given. You are required to find out the outcome which should come in place of question mark (?) in each of the given sets of sequence.
