For financial planner
40% in stock, and 60% in money fund
For banker
100% with 5% , in 0.5 years
Then if N= 5000
Planner yield= N•(4/10)• 7/100 + N(6/10)•(4.5/100)
. = N• (28/1000 + 27/1000)
. = 5000(55/1000)
. = 275
Banker yield= N • (1+ 5/100)^ 2 - N
. = N• (1.05 ) - N
. = 5512.5 - 5000
. = 512.5
Then answer is
Highest yield is Banker's advice
