In a certain coding language, Tour is written as 4156, Screw is written as 73698 and Tear is written as 4962. How will the word Sweater be written in that language?

Sweater is written as 7892496.

Each letter has a fixed digit: S=7, w=8, e=9, a=2, t=4, r=6.

These follow from Tour = 4156 and Screw = 73698 (t=4, r=6, S=7, c=3, e=9, w=8) with a=2.

Sweater = S w e a t e r.

Replacing: 7, 8, 9, 2, 4, 9, 6.

So Sweater = 7892496.
