please don't open threads for a single question.
o0 i thought he asked the first digit of that no,
@Erudite.Cat said:A number has 6 different digits. If the last digit is moved to the front, then a new number is formed which is exaclty 5 times the old number. With which number did we start?
Kind of a knowledge based question. It is the property of 7 inverse (reciprocal of 7)
1/7 = 0.142857... Concentrate on 142857. If you shift 7 from its current position, you'd get the fifth multiple of original number.
Just play around with 142857 keeping the relative order same i.e. 428571, 285712, 571428 and you'd see the magic.. Happy learning!
i mean even if the last digit becomes the first digit ... ei
