Sunday Times Teaser 2683 – House to House

by Robin Nayler

Four families (A, B, C and D) live in this order on a road with consecutively numbered houses on one side only.

The number of houses between A’s and B’s houses is a multiple of the number of houses between B’s and C’s houses.

The number of houses between A’s and C’s houses is the same multiple of the number of houses between C’s and D’s houses.

A’s house number is in the teens and D’s house number has the same digits as A’s but in reverse order.

What are the four house numbers?
