The number of 5-digited number which are not divisible by 5 and which consists of different odd digits is
- A \(24\)
- B \(32\)
- C \(96\)
- D \(120\)
Answer & Solution
Correct Answer
(C) \(96\)
Step-by-step Solution
Detailed explanation
The numbers are formed from the digits \[ 1,3,5,7,9 \] Total no. of five digits \(=5\) ! Total no. of five digits divisible by \(5=4\) ! \(\therefore\) Required number of ways \[ =5 !-4 !=4.24=96 \]
