Sunday Times Teaser 2670 – Answers on a Postcard

by Andrew Skidmore

I have four two digit whole numbers, none of which is a multiple of three.

These numbers use eight consecutive digits in total and the digits in three of them are consecutive in some order.

I have calculated their sum and product and, after consistently using different letters to represent different digits, I find that these translate to SUM and PRODUCT respectively.

What number does POSTCARD represent?
