The difference between two numbers is 14 and their sum is 48. What is the product of these two numbers?

Explanation

x-y=14, x+y=48. 2x=62 -> x=31. y=17. 31*17=527. Wait, recalculate: 2x=62, x=31. y=48-31=17. 31*17=527. Let’s check 539: 539 is wrong. Let’s use numbers 31 and 17. 31+17=48, 31-17=14. 31*17=527. Re-check options. Actually, if sum is 48 and difference is 14, numbers are (48+14)/2=31, (48-14)/2=17. 31*17=527. Since 527 is not an option, check sum 50, diff 14? 32, 18. Product 576. Let’s provide 527 and update option.
