Since the benefit-cost is highest for the stock of S. Products, investment should be made in S Products.

Explanation of Solution

Given information:

Minimum rate of return = 10%.

Six stocks are available.

Calculate the ratio of PW of benefits and PW of costs for each stock.

B/CratioforW.H.=PWofbenefitsPWofcosts=1.25(P/A,10%,4)+32(P/F,10%,4)23.75=1.25(3.170)+32(0.6830)23.75=25.818523.75=1.0871

B/CratioforF.F.=PWofbenefitsPWofcosts=4.50(P/A,10%,4)+45(P/F,10%,4)45=4.50(3.170)+45(0.6830)45=4545=1

B/CratioforM.M=PWofbenefitsPWofcosts=0(P/A,10%,4)+42(P/F,10%,4)30.6250=0+42(0.6830)30.6250=28.68630.6250=0.9367

B/CratioforS.P.=PWofbenefitsPWofcosts=0(P/A,10%,4)+20(P/F,10%,4)12=0+20(0.6830)12=13.6612=1.1383
