In a three digit number the 2nd digit is 4 times as big as the 3rd digit and the 1st digit is 3 less than the 2nd digit. what are the two possible three digit numbers?

Say that xyz is your number,  then y=4z and x+3=y

Since it is a multiple of 4, y has to be 4 or 8, which means z has to be 1 or 2, since it is 1/4 of y and then since x is 3 less than y, x would have to be 1 or 5...so the numbers are141 or 582
