Rs 25,ooo is invested in two fixed deposits X and Y offering compound interest at 6%pa and 8%pa respectively.If the total amount of interest accrued through both fixed deposits is rs 3518, the amount invested in scheme X

1) 12,000
2) 13,000
3) 15,000
4) cannot be determined

• First of all.., correct the time period as 2 years...
  x+y=25000
  x(1+ 6/100)^2-x + y(1+ 8/100)^2-y=3518;
  x(2809/2500 -1)+y(2916/2500 -1)=3518;
  309x+416y=3518*2500;
  309x+416(25000-x)=8795000;
  309x+10400000-416x=8795000;
  107x=1605000;
  x=15000;
  So,Amount Invested in Scheme X=15000/-
