A) 144
B) 72
C) 288
D) 720
Correct Answer: D
Solution :
[d] Terminal digits are the first and last digits. \[\therefore \] Terminal digits are even \[\therefore \] 1st place can be filled in 3 ways and last place can be filled in 1 ways and remaining places can be filled in \[^{5}{{P}_{4}}=120\] ways. Hence the number of six digit numbers so that the terminal digits are even, is \[3\times 120\times 2=720\]You need to login to perform this action.
