Philip, Daphne and I live in different houses on Teaser Drive. Philip lives at number 1 and the houses are then numbered consecutively along one side of the road. The sum of the house numbers strictly between Philip’s house and mine is equal to the sum of the house numbers strictly between my house and Daphne’s. Furthermore, the digits of Daphne’s house number add up to the same total as the digits of my house number.
What is my house number and what is Daphne’s?
