Perplexity

This week, a census-taker asked a woman her age. "If you multiply the day of the month on which I was born by the number of the month, you get twice my age in completed years," she said. "And if you subtract the month from the day, you get the difference between the two digits of my age. Yet if you add all the digits in the day and month, you get the same answer as adding the last two digits of my year of birth."

"Just fill in the form, madam," said the census-taker. How old is she?
