Answer:
Expected return = 8.2%
Explanation:
A portfolio is a collection of assets/ investment. The return on a portfolio is the weighted average of all the return of the individual assets weighted according to the percentage of total funds allocated to each assets.
Expected return on portfolio:
E(R) =( Wa*Ra) + (Wb*Rb) + (Wc*Rc) + Wn*Rn
W= Weight i.e proportion of fund invested in each asset class
Wa = 20%, Wb- 40%, Wc- 20%
Ra-2%, Rb-18%, Rc- 3%
E(R) = (0.2 *2%) + (0.4× 18%) + (0.2*3%) = 8.2%
Expected return = 8.2%
