Dear jee king
identical digits can be at 100th and 10th position or at 10th and unit place
case 1
identical digit at 100th and 10th posiition
0 can be at 100th position so these 2 position can be filled by 9 ways
and unit place can be filled by 9 ways
total ways =9*9 =81
case 2
identicle digit at 10 th and unit position
so total ways =81+81 =162
