I think the answer is E. none of these
My answer is 240. Here's the solution.
We know that a number is divisible by 4 if the last two digits of the number is a multiple of 4 or the number is 0.
So the possible numbers would end with 12,16,24,32,36,42,44,52,56,64.
So if we are taking a t digut number then the number if digits left would be 3 as the rest two would be occupied by anyone of the above given numbers.
_ _ _ 1 2
The first blank from left has 4 options remaing . The second blank has 3 options remaining and the third blank has 2 options. Here options symbolizes the numbers the blank can take. (I have kept in mind that repition is not allowed).
So total no.of selections for one number is 4×3×2=24.
We have 10 selections. So total numbers divisible by 4 is 240
