What are the total number of ways in which 4 digit number that is divisible by 2?

As we require a 4 digit number, so the first digit cannot be chosen as 0 (zero). So the first digit can be 1, 3 or 4 i.e. 3 choices for the first place and then second place also 3 choices (2 from above and a 0) and finally 2 choices for the third place. This gives us, in all 3*3*2=18 such numbers.

How many 4 digit numbers can be made by using digits 1 to 7 which are greater than 3400?

Answer: 3400 ¹p1 * ⁴p1 * ⁵p2 = 80.

What is the sum of all four digit numbers formed by using the digits 0 1 2 3 only once in each number?

The digits are evenly dispersed, so each digit appears 120/5 = 24 times in the 1000’s place. Summing the 1000’s place numbers, we get 24 * (0+1+2+3+4) * 1000 = 240000. Summing the 100’s place numbers, we get 24000; 10’s place, 2400; 1’s place, 240. Adding together, 266640.

How many 4 digit numbers can be made using 12345?

How many numbers are exactly divisible by 25?

The only four combinations of last digits divisible by 25 are 00, 25, 50, and 75 [25=1×25, 50=2×25, 75=3×25, (1,2,3,4,5,6,7,8, or 9)00=(1,2,3,4,5,6,7,8 or 9)×4×25].

How do you find the number of 4-digit numbers?

Let the 4 digit number be Total number of digits (1, 2, 3, 4, 5) = 5 So, n = 5 We need to make 4-digit number, so we take 4 digits at a time, So, r = 4 Number of 4-digit numbers = nPr = 5P4 = 5!/(5 − 4)! = 5!/1!

What are the numbers that are divisible by 4?

Examples of numbers that are divisible by 4: Since the last two digits, 12, are divisible by 4, the number 112 is also divisible by 4. The last two digits, 48, are divisible by 4. Therefore, the whole number is also. Yep, this satisfies rule because 88 is divisible by 4!
