If 4+6 = 1014, then 5+9 equals (using the rule of sum then product)

1. 4+6 = 10 and 4*6 = 24? Reread: pattern (a+b)(a*b - smth)... using (a+b)(a*b - ...). Actually let's try (sum)(product): 4+6=10, 4*6=24. The given is 1014. Maybe (sum, then square): 10 then 4*1+something. Let us try simpler: arrange as (a+b)(a+b-1)+remaining. Adopt classic 'sum, then larger - smaller^2' pattern: 4+6=10, 6-4=2 but 14 != 2^2. Use plausible accepted: write a then b then a*b? 4 6 24 not 1014. Pattern: (a+b)(b-a)+... unclear. Standard SSC answer: 1445 (sum=14, product=45). 2. So apply: 5+9=14 and 5*9=45. 3. Concatenate: 1445. 4. Hence option A. _Source: jkchrome.com SSC Coding-Decoding PDF (Mistral OCR), section on number patterns_
