Solution :
Calculation of the expected return of Asset A :
The expected return of an Asset can be calculated using the formula
Expected Return = ( P1 * R1 ) + ( P2 * R2 )
Where
P1 = Probability that the economy will boom ; R1 : Expected Return if the economy Booms
P2 = Probability that the economy will bust ; R2 : Expected Return if the economy busts
As per the information given in the question with respect to Asset A we have:
P1 = 0.25 ; R1 = 12 % ; P2 = 0.75 ; R2 = 6 %
Applying the above values in the formula we have Expected return of Asset A as
= ( 0.25 * 12 % ) + ( 0.75 * 6 % )
= 3 % + 4.5 % = 7.5 %
Thus the Expected Return of Asset A = 7.5 %
Calculation of the expected return of Asset B :
The expected return of an Asset can be calculated using the formula
Expected Return = ( P1 * R1 ) + ( P2 * R2 )
Where
P1 = Probability that the economy will boom ; R1 : Expected Return if the economy Booms
P2 = Probability that the economy will bust ; R2 : Expected Return if the economy busts
As per the information given in the question with respect to Asset B we have:
P1 = 0.25 ; R1 = 4 % ; P2 = 0.75 ; R2 = 18 %
Applying the above values in the formula we have Expected return of Asset B as
= ( 0.25 * 4 % ) + ( 0.75 * 18 % )
= 1 % + 13.5 % = 14.5 %
Thus the Expected Return of Asset B = 14.5 %
Calculation of expected return of a portfolio :
The formula for calculating the expected return of a portfolio is
RP = ( RE * WE ) + ( RF * WF )
where
RA = Expected Return of Asset A ; WA = Weight of Asset A
RB = Expected Return of Asset B ; WB = Weight of Asset B
As per the information given we have
RA = 7.5 % ; WA = 0 % = 0.00 ; RB = 14.5 % ; WB = 100 % = 1
Applying the above values in the formula we have
= ( 7.5 % * 0 % ) + ( 14.5 % * 100 % )
= 14.5 %
The expected return for the portfolio is = 14.5 %
The solution is Option d. 14.5
