Who is asking: Student
I have 6 digits. My hundred thousands is 1 less than my 1 digit, 8 greater than my thousands digit, twice my tens digit, and 4 times my hundreds digit. My ten thousands digit is 0. What # am I?
Suppose that the number is
that is f is the units digit, e is the ten's digit, c is the hundred's digit, etc. The first clue then says
a = f - 1
and the second clus says that
a = c + 8
Since a is a one digit number, c can only be 0 or 1. If c were 1 then a would be 9 and the first clue would then make f = 10. But f is also a one digit number. Hence c must be 0.
Can you do the rest now?
