The number of five digit numbers that are divisible by 6 which can be formed by choosing digits from \(\{0,1,2,3,4,5\}\), when repetition is allowed, is
- A 648
- B 540
- C 1296
- D 1080
Answer & Solution
Correct Answer
(D) 1080
Step-by-step Solution
Detailed explanation
If number is divisible by 6 , then it should be an even number and divisible by 3 also, so sum of the digits should be divisible by 3 . Now last digit can be fill by 0 or 2 or 4 . First place can be filled by 5 choices (except 0 ) second and third can be filled by 6 choices. Now…
