Question

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

• A. 7
• B. 10
• C. 20
• D. 12

Answer 1

The correct option is A 7

The numbers from $1$ to $100$ which are exactly divisible by $4$ are:-

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

But each number should have $4$ as its digit.

Therefore, the required numbers are $4,24,40,44,48,64,84$.

Clearly, 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.
