The number of numbers between 2000 and 5000 that can be formed with the digits 0,1 , 2, 3, 4 (repetition of digits not allowed) and are multiple of 3 is
- A 48
- B 30
- C 24
- D 32
Answer & Solution
Correct Answer
(B) 30
Step-by-step Solution
Detailed explanation
Number between 2000 and 5000 is a 4 digits number. For the multiples of 3, the sum of digit must be divisible by 3 . There are only 2 ways of selecting the digits so that 4 digit number with the given digits can be formed, i.e. 0, 1, 2, 3 and 0, 2, 3, 4 . The number of ways of…
