From New Scientist #1171, 6th September 1979 [link]
In this addition sum, with letters substituted for digits, there is, I’m afraid, a mistake. The first two lines across are correct, but in the third line across there has been a mistake and one of the letters is incorrect. Apart from this unfortunate error (due of course to Uncle Bungle) each letter stands for the same digit wherever it appears and different letters stand for different digits.
Find the mistake and write out the correct addition sum.
Note: When it’s talking about “first two lines across” it is referring to the summands, and the “third line across” refers to the result of the sum.
