Question

The license plate on Mr. Smith’s car contains five different digits. However, his son installed it upside down. Yet, it still shows a five-digit number. The only thing is, the new number is 10692 more than the original number. What was the original license plate number?

Answer 1

If you turn the numbers upside down, the only readable numbers are 0,1,6,8,9

80691 - 16908 = 63783 

so it's 16908
