(1) \(\frac{p}{10^4}\) has a thousandths digit of 6.

(2) \(0.1p\) has a hundreds digit of 6.

(1) \(\frac{p}{10^4}\) has a thousandths digit of 6.
Let \(\frac{p}{10^4}\) be ab.cd6efg, so p=ab.cd6e*10^4=abcd6e.fg.
The tens digit of abcd6e.fg is 6
Suff

(2) \(0.1p\) has a hundreds digit of 6.
Let 0.1p=ab6cd, so p=ab6cd0, so tens digit is d whhich cannot be determined with given info

How can you guess that the thousand digit after decimal is 6.

p/10^4 can be 6234.mnop then how can you say tens digit is 6.

secondly why cant p/0.1= abc6.mnop then tens digit is 6.


please clarify

(2) \(0.1p\) has a hundreds digit of 6.
Let 0.1p=ab6cd, so p=ab6cd0, so tens digit is d whhich cannot be determined with given info
