NIMCET 2018 Question Paper with solutions

Time on the watch is quarter to three, i.e. 2 : 45

Clearly, the hour hand points South-West direction.
Effective Memory Access Time (EAT)
= Hit Ratio * (Cac memory time + Memory access time) + (1-hit) * (Cache memory time + 2 * Memory access time )
EAT = .15 (0.01 + 10) + (1 - 0.15) (0.01 + 2 x 10)
= (0.15) (10.01) + (0.85) (20.01)
= 15015 + 17.0085
= 18.51 milliseconds
