Yeah..I also got this but answer given is different

Answer is 0.1

---

Yes its 0.1 , because they had used the concept of spatial locality.

On referencing 100,  the complete cache block will be available   (1 MISS)

Since, each cache block contains 4 32-bit words and we have 4 cache lines and four blocks per cache lines..(32 bit word = 4  eight bytes )

Hence on referencing to 100 ....blocks from 101-115 will be available 

So, on refering 104,108,.........108,103 . (all we be HIT)

cache may look like this...:

100 101 102 103	104 105 106 107	108 109 110 111	112 113 114 115

Correct me If I am wrong somewhere!!
