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?
