1. ---> P is odd , 1<P<=9 --> P can be 3,7,9 ..only 3 satisfies---->suff
2. 2 is a factor of 26, 3 is a factor of 36 --->insuff

P is a number between 1 and 9.
P factor of P3
For all values of P from 1 to 9,
13,23,33,43,53,63,73,83,93 only P=3 satisfies. -- sufficient

P factor of P6
16,26,36,46,56,66,76,86,96

P=3 and P=6 satisfy -- insuff

P+ve and P>1

P is a factor of P3. P goe in P 1 ttimes and left with 3. P must factor 3. Since P is not equal to 1 it ahs to be equal to 3. Suff

Same logic, now p must factor 6. It can be 2,3,6 etc. Hence insuff

how do we know P is not 11 and it is 9?

11*3=33? which is two digit integer?
so how do we know that P is unit integer?

duhhh..I just realized that the integer is P3 ie. as in 23 or 33 43 etc....

OK

so lets see...

P is a factor of P3 and we know P3 is odd, if p 63, 6 is not a factor of 63! and like wise all numbers except 3 dont work... (I) is suff

(II) is insuff cause if 26 well 2 is a factor of 26, so is 36, 3 is a factor of 36...clearly Insuff!

A it is..
