The solutions #4801 and #4802 are correct. Marvelous!
#4803. A number consists of two digits. The sum of the digits is 9. If 63 is subtracted from the number, its digits are interchanged. Find the number.
#4804. A fraction becomes
when 1 is added to both, its numerator and denominator. And, it becomes when 1 is subtracted from both the numerator and denominator. Find the fraction.It appears to me that if one wants to make progress in mathematics, one should study the masters and not the pupils. - Niels Henrik Abel.

Re: 10 second questions
Lots of them, if I do not make a math mistake then I will make a copy mistake. If you do not make a copy mistake then I will read the question wrong. We can not be perfect.
