36   15   3
12    3    n
If 'n' is the resultant of the first row, what will be the resultant of the second row?

Rules
(i) (odd number) + (Composite odd number)
(ii) (Even number) + (Odd number)
(iii) (Even number) ? (Perfect square number), then (Perfect square number) - (Even number)
(iv) (Odd number) ÷ (Prime odd number)
(v) (Odd number) - (Even number)
Solution
1st Row 36   15   3 ? 36 + 15 = 51       [rule (ii)]
?     51 ÷ 3 = 17     [rule (iv)]
          = n
2nd Row 12   3   n ? 12   3   17
?         12 + 3 = 15   [rule (ii)]
?       15 ÷ 17 = 15/17     [rule (iv)]
? Resultant of second row = 15/17
