it is a 6 digit number. there is no repetition of digits. It is divisible by 5 and is more than 3000,000. The digit in the hundreds place is 3 more than the digit in the ones place. The digit in the ten thousands place is 3 times the digit in the hundred thousands place. The digit in the thousands place is half the value of the digit in the hundreds place.
the difference between the digits in the tens place and the thousands place is 2.

Please proofread this problem. If the number is more than 3,000,000, then it has 7 or more digits.

since no mention is made of the millions digit, let's assume it is in fact 6 digits and more than 300,000.

10,000 = 3*100,000, so 100,000 digit is 3, 10,000 = 9. Anthing other than 3 must be greater than 3, so 3 times it will exceed 9.

93xxxx

Divisible by 5 means the ones digits is 5 or 0:

39xxx0 or 39xxx5

hundreds = ones + 3, so 3 or 8

39x3x0 or 39x8x5
no repeats means 39x8x5

thousands = 1/2 of hundreds = 4
3948x5

thousands - tens = 2 or -2

394825
394865
