I am three - digit number. My ones digit is 4 less than my tens digit. My hundreds digit is an even number less than 4. What number i am?

Answer 1

Let the number be ABC
The only even number less than 4 is 2, so
2BC
B-C = 4
B = C+4 , so let C = 0, 1, 2, 3, 4, 5

your number could be:
240, 251, 262, 273, 284, or 295
