Q6. How many 5-digit numbers can be formed which contain only one times the digit ‘3’.
25,842
29,889
26,729
26,889
29,349
Solution:
If first digit is ‘3’ then remaining numbers can be formed in ways = 6561 ways
If first digit isn’t ‘3’ then first digit can be formed in 8 ways (excluding 3 and 0). Now out of remaining four one should be ‘3’ and remaining three digits can be formed in 9³ ways = 729 ways
So, total ways to form five digit number in which first digit isn’t ‘3’
= 4 × 8 × 729 = 23,328
‘4’ is multiplied because the digit ‘3’ can take four places.
And, Total ways to form five digit numbers in which first digit is ‘3’
= 6561 ways
Total number of ways = 23,328 + 6561 = 29,889

Number of ways = 5 × 5 × 1 = 25
Total number of ways = 30 + 25 = 55
