| Question 431877:  An investor had a total of 25,000 put into a portfolio of stocks, bonds, and mutual funds. In one year, he earned 8% on the stock investment, 10% on the bond investment and 6% on the mutual funds investment. The annual(simple interest) return was $1860. if the amount invested in the mutual fund was twice the investment in bonds, then how much did he originally put in each of the three individual investments?

You can put this solution on YOUR website! Bonds ------ $x -------10% Mutual funds -$2x-------6%
 Stock -------(25000-3x)---8%
 Interest = 1860
 10x+6*2x+8(25000-3x)= 1860*100
 10x+12x+200000-24x =186000
 -2x=-14,000
 x= $7000 ------- Bonds
 Mutual funds --- 2x= $14,000
 Stocks --------- $4000
 CHECK
 7000*0.1+14000*0.06+4000*0.08=1860
