Answer» Answer: 800,1200 at 8%,6% INTEREST respectively. Step-by-step explanation Let's assume that x was borrowed from a guy where interest is 8% per annum and assume 2000-x was borrowed from a guy where interest is 6% per annum. so TOTAL interest=x*(8/100) + (2000-x)*(6/100) = 136 ==> 8x + 6*(2000-x) = 13600 ===> 2X +12000 =13600 ===> 2x = 1600 ===> x = 800 so amount taken at 8% is 800 amount taken at 6% is 2000-800=1200 |
