Question

my thousandth digit is 3 times my hundredth digit. The sum of the tenth digit and unit digit is 1 less than my thousandth digit. My hundreth digit is 2 less than my tenth digit. What four digit I am?

Answer 1

hint: consider the cases where the thousands digit is three times the hundreds digit... so
Case 1: the thousands digit is a 3 while the hundreds digit is a 1
Case 2: the thousands digit is a 6 while the hundreds digit is a 2
Case 3: the thousands digit is a 9 while the undreds digit is a 3
Then work on the Tens digit in each of these three cases : )

Answer 2

my thousandth digit is 3 times my hundredth digit
---> only possible cases: 31xx , 62xx, and 93xx

My hundredth digit is 2 less than my tenth digit.
---> only possible cases: 313x , 624x, and 935x

The sum of the tenth digit and unit digit is 1 less than my thousandth digit
---> possible cases: 6241, 9353

6241 or 9353
