the fact that (again in base ten), a perfect square will always end in one of: 00, 01, 04, 09, 16, 21, 24, 25, 29, 36, 41, 44,49, 56, 61, 64, 69, 76, 81, 84, 89, 96 thats what i found ...so the only possibility left is - 96 at the end....and if ans is none then i dnt knw how to rule out the possibility of the number ending with 96 however rest of the possibilities can also ruled out by the following facts for perfect square : 1) no square ends with 2,3,7 and 8 2) in last two digits there is atleast one digit which is even.
gud gud....bt if u knw dt D.R. of a perfect square is always 1,4,7,9....dn d story is vry easy 2 undrstnd....nw wtvr d number may be.....D.R. will be 9+0+9+1+9+2+9+3+9+4+9+5+9+6=84=12=3 So,dr will b no number...

however rest of the possibilities can also ruled out by the following facts for perfect square :
1) no square ends with 2,3,7 and 8
2) in last two digits there is atleast one digit which is even.
cont....
3) all squares ending with 1 or 4 have an even no. in the tens place
4) no number can be a perfect square unless its DR is 1,4,7 or 9.
