Question

How many numbers from 1 to 100 are there each of which is not only exactly divisible by 4
but also does not have 4 as a digit?

Answer 1

Answer:

Step-by-step explanation:

Numbers containing 4 but not divisible by 4 are : 14, 34, 41, 42, 43, 45, 46, 47, 49, 54, 74, and 94, that is 12 numbers from 1 to 100. 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44,48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96 and 100. Of these only 7 numbers namely, 4, 24, 40, 44, 48, 64, 84 have 4 in them.

Answer 2

Answer:

There are 7 such numbers from 1 to 100 and rach of which is not only exactly divisible by 4 but also have 4 as a digit.

Step-by-step explanation:

we have given in question

The numbers from 1 to 100 which are exactly divisible by 4, These are mentioned below

4,8,12,16,20,24,28,32,36,40,44,48,52,56,60,64,68,72,76,80,84,88,92,96,100

But, as we have given in the question that each number should have 4 as its digit.

Therefore, the numbers which are required which have 4 as a digit are 24,40,44,48,64,84.

Hence after counting these numbers, there are 7 such numbers.

Hence, there are 7 numbers from 1 to 100 each of which is not only exactly divisible by 4 but also has 4 as a digit.
