Number of five digit numbers that can be formed using the digits 1,2,3,4,5,6,7,8,9 in which one digit . The first digit is 7. There are 100 of such numbers. The first digit is not 7 but the second is. There are $8\cdot10=80$ such numbers. The first and second digit are not 7 andthe last one is 7. There are $8\cdot9=72$ (the first must be nonzero) such numbers, which gives the desired 252. We will calculate how many 4-digit numbers there are without a 5. Step 2: For each digit, there is 9 choices (0-9, excluding 5). The first digit also can't be 0. So there would be 8 9 9*9=5832 numbers without a 5. Step 3: Subtract the total number of 4-digit numbers from the numbers without a 5. 9000-5832=3168. dyuthivallamsetty. report flag outlined. Answer: 18.

How many $4$-digit numbers can be formed from the digits $1,2,3,4,5,6,7$ if each digit can only be used once and sum of digits is even? 1 How many ways are there to form a 16-digit number in which each digit appears at least once
This time we want to use 2 digits at the time to make 2-digit numbers. For the first digit, we have 4 choices and for the second digit, we have 3 choices (4 - 1 used already). Using the counting principle, the number of 2 digit numbers that we can make using 4 digits is given by 4 × 3 = 12 The above problem is that of arranging 2 digits out of .The first two digit natural number divisible by 7 is 14. The last two digit natural number divisible by 7 is 98. The sequence of numbers 14, 21, 28, .., 98 which is divisible by 7 is an arithmetic progression with 1 s t term 14 and common difference of 7. Step 2 : Finding the number of terms in an arithmetic progression
Suppose that repetitions are not allowed. There are $6 \cdot 5 \cdot 4 \cdot 3 $ numbers with $4$ digits , that can be formed from the digits $1,2,3,5,7,8$. How many of them contain the digits $3.how many 2 digit numbers contain the number 7 Total ways to write this: 36 = 729 3 6 = 729. Don't include the number '1': 26 = 64 2 6 = 64. Thus, the number of ways can be calculated by take away ways that don't include 1,2 or 3, which is. 729 − 3 ∗ 64 + 3 = 540 729 − 3 ∗ 64 + 3 = 540. since 111111, 222222 and 333333 are counted twice. How many 3-digit numbers containing at least one digit of 7? Answer is 199. The set of three-digit numbers starts at 000 and goes to 999.
