My tenths digit is twice greater than my thousandths place.My hundredths digit is the sum of my tenths and thousandths digits.Who am i?

Answer 1

thousandth digit --- t
tens digit --------- 2t

hundredth digit ---- t + 2t = 3t

well, digits can only range from 0 to 9
let's rule out t = 0 , since that would not be a sensible number

then tenth digit is obviously an even number
so it could be 2,4,6,8
which means that t can only be 1, 2, 3, or 4

if t = 1, # is 132x , where x is any number from 0 to 9
if t=2, # is 264x
if t = 3, # is 396x

So you have 30 possible numbers
