Doubt1: Is question properly framed?

Doubt2: Assuming Doubt1 says yes, Say there are 5 processes $P_1,P_2,P_3,P_4,P_5$ and say all have total execution time of 10 units. Now out of this 10 units, 3 units will be for I/O of each process, but since I/O can proceed in parallel, So, say all processes arrived at t=0, then only first 3 units of time CPU will be idle and hence CPU Utilisation is (35/38)*100.Is this correct?
