The number of digit numbers which are divisible by , with digits from the set and the repetition of digits is allowed, is _____.
- A 600
- B 700
- C 725
- D 625
Answer & Solution
Correct Answer
(D) 625
Step-by-step Solution
Detailed explanation
Option for last two digits are \((12),(24),(32),(44)\) are \((52)\).
\(\therefore\) Total number of 5 digit numbers
\(=5 \times 5 \times 5 \times 5=625\)
\(\therefore\) Total number of 5 digit numbers
\(=5 \times 5 \times 5 \times 5=625\)
