# Sunday Times Teaser 2680 – Yesterday

*by Peter G. Chamberlain*

On a new style of mobile phone each of the number buttons 1 to 9 is associated with either two or three of the letters from A to Z.

The letters are in no particular order, all letters appear and none appears more than once.

M, T and U are on the same button and the numbers typed for SUNDAY, TIMES and TEASER are all multiples of 495.

What number has to be typed for SATURDAY?

Multipliers with 495 must all be odd numbers as a result of which we have Y=S=R=5 from which we can continue to solve the puzzle by trial and error under the given constraints.
