Suppose the answer to the above question is A, and the integer part of A is b. Swap the ones and hundreds digits of a three-digit number to get a new three-digit number. Knowing that the product of these two three-digit numbers is equal to 115237+b, what is the sum of these two three-digit numbers?
设上题答数是A，A的整数部分是b．将一个三位数的个位数字与百位数字对调，得到一个新的三位数．已知这两个三位数的乘积等于115237+b，那么这两个三位数的和等于多少．
