Question 22
Edison makes three-digit numbers with matchsticks. Viewed upside down, a number may become a new number; for example, 108 becomes 801. He forms a three-digit number whose upside-down view is another three-digit number, larger by 825. Find the original number. The digit shapes 0–9 are shown below.
Turn the whole numeral through 180 degrees in its plane, using the shown matchstick shapes. Both original and new numbers must have exactly three digits.
Input: enter the requested whole-number answer without units. Leading zeroes from the paper grid may be omitted.
