From "If the number in the hundredth place is equal to 1 10", we can get:
10c+b+ 10a+b = 1 10
Where (10a+10c) =10 (a+c), and the mantissa is 0.
Then (b+b) mantissa is 0.
B and c are odd numbers.
Then b=5.
From "the number on the tenth place and the number on the fourth place are two consecutive odd numbers arranged from big to small"
c=3
Then a=7
This three-digit number is 753.
