AFM Kaplan exam kit Q2 and Q9

Dear Tutor,

I would like to know the difference between CAPM formula mentioned in the questions above. Q.2, THe CAPM is 3.5%+1.748(10%-3.5%), while in Q.9, it is 4.5%+1.53(6%). Perhaps, in short, what are the difference between market risk premium (Q9) and market return(Q2). Are they different in calculating CAPM ?? Thank you.
