Question 8101
let one amount be x then the second amount is 30000-x 
Interest on first ammount i=ptr/100 
(x*1*3 )/ 100. ----------------------equation (1) 
Interest on second amount i=((30000-x)*1*4.1 )/ 100-------------equaion (2) 
so total interest is equation (1) + (2) 
3x/100 + 4.1(30000-x)/100 = 1091.73 
after cross multiplication we get
3x+4.1(30000-x)= 109173
3x+123000-4.1x = 109173 
-1.1x = -13827 
------> x=12570 
hence first amount is $12570 and second amount is $17430.00.
