In the question the number given is 327,902. So for this number we see that 7 lies in the thousands place and hence the actually 7 stands for 7000 in the number 327,902. But if we shift the 7 from the thousands place to the tens place, it simply stands for 70. There is a huge difference of 6930 if the 7 changes its position from the thousands place to the tens place. The given number will change dramatically and in case of any equation it will give a different result.
