You can avoid calculation of compounded interest here.

$8,500 for one year at a simple annual interest rate of 5 percent = 10% *8500= 850 so 5% = $$\frac{850}{2}$$ = 425 Now$12,000 were invested for one year at a simple annual interest rate of 8.5 percent, then it would earn 8%*12000+0.5%*12000 = 960+60=$1020 This total is coming as 425+1020 = 1445. Thus answer has to be greater than 1445.
