Expected return of a portfolio using beta. The beta of four stocks$-$P$,$ Q$,$ R$,$ and S$-$are $0\mathrm{.}60,0\mathrm{.}85,1\mathrm{.}20,$ and $1\mathrm{.}35,$ respectively and the beta of portfolio $1$ is $1\mathrm{.}00,$ the beta of portfolio $2$

is $0\mathrm{.}90,$ and the beta of portfolio $3$ is $1\mathrm{.}12.$ What are the expected returns of each of the four individual assets and the three portfolios if the current SML is plotted with an intercept of $3\mathrm{.}0\%$

$($risk$-$free rate$)$ and a market premium of $11\mathrm{.}0\%($slope of the line$)?$
