Jeanne Lewis is attempting to evaluate two possible portfolios consisting of the same five assets but held in different proportions. She is particularly interested in using beta to compare the risk of the portfolios and, in this regard, has gathered thedata:

		Portfolio Weights (%)
Asset	Asset Beta	Portfolio A			Portfolio B
1	1.25		7			29
2	0.72		31			7
3	1.25		11			20
4	1.11		9			20
5	0.95		42			24
	Total		100			100

a.Calculate the betas for portfolios A and B.

b. Calculate the required rate of return for portfolios A and B
