A Tk. 500 investment and a Tk. 1,500 investment have a combined yearly return of 5 percent of the total of the investments. If the Tk. 500 investment has a yearly return of 7 percent yearly return does the Tk. 1,500 investment have?
সমাধান
সঠিক উত্তর: Option A
total investment = 500+1500=2000 tk 8.5 percent of the total of the investments = (8.5 / 2000) X 100 =170 at 7 percent , annual return of 500 tk = 35 tk renains= 170-35=135 tk so, percent of yearly return of 1500 tk is = (135/1500) X 100 = 9%
