Let a,b,c be distinct digits. Consider a two digit number 'ab' and a three digit number 'ccb', both defined under the usual decimal number system, if(ab)^2=ccb and ccb>300, then the value of b is

1) 1
2) 0
3) 5
4) 6
5) 2

• 1, ccb>300 & it is a perfect square
  So ccb value be only 441. So b value be 1
