if yearly return of 8.5% is obtained from the combined investment of $4000, interest earned = 4000×(17/200) = $340
 
if yearly return of 7% is obtained for an anoumt $1000, then interest earned = 1000×(7/100) = $70
 
interest earned in amount $3000 = $340 - $70 = $270
 
percentage of yearly return = (270/3000)×100  = 9%
