345 460 ?
Answer: 577
Solution (rule used): each bottom number = (square of column sum) + (10 × top number of that column)
– Column sums: col1 = 5+3+9 = 17 → 
. Add 
top element (5): 
. This is short of 345 by 6 — add the middle element (3) → 
.
– col2: sum = 6+4+10 = 20 → 
. Add 
→ 
(matches).
– col3: sum = 7+5+11 = 23 → 
. Add 
→ 
. Now adjust by subtracting the middle element (5) to keep the same small correction pattern used in col1: 
.
Thus option (4) 577.
