After moving the decimal point of a decimal one place to the left, the number obtained is 13.86 less than the original number. What is the original number

If the original number is x, the decimal point will be shifted one place to the left to X / 10
According to the original conditions: X - (x / 10) = 13.84
x=13.84*(10/9)=15.4
