There are altogether \(10\) digits \({0,1,2,3,4,5,6,7,8,9}\) for a single place for any number
For three digit numbers there are altogether \(3\) places Since we cannot use \({0,2,4,6,8}\) the three digit number has
to be composed from \({1,3,5,7,9} = 5\) digits hence total number \(= 5*5*5 =125\)
option E
