1.	3)How many three digit natural numbers are divisible by 4?
Answer» From 1- 40 , 10 numbers divisible by 4 From 41–80,10 more numbers From81-100, 5 more numbers So between 1–100 ,25 numbers are divisible by 4. So three digits numbers comes in the range of 100 and 1000. Therefore the number of digits divisible by 4 will be 25*9 =225 225 +1=226 1 is added because 100 is also a three digit number divisible by 4.

Answer»

From 1- 40 , 10 numbers divisible by 4

From 41–80,10 more numbers

From81-100, 5 more numbers

So between 1–100 ,25 numbers are divisible by 4.

So three digits numbers comes in the range of 100 and 1000.

Therefore the number of digits divisible by 4 will be 25*9 =225

225 +1=226

1 is added because 100 is also a three digit number divisible by 4.
