Sol. Ans.(c).

Between 1 and 100 there are 19 such integers which have 4 as a digit – 4, 14, 24, 34, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 54, 64, 74, 84 and 94.

Out of these, only 7 integers – 4, 24, 40, 44, 48, 64 and 84 are divisible by 4.

So correct answer will be 19 – 7 = 12. A mechanical question but can be done.
