Question

Divide 4500 into two parts so thqt the simple interest on the first when deposited for one year at 9% per anum and that on the second when deposited for 3 years at 15% per annum in a bank are the same

Answer 1

Answer:

Step-by-step explanation:

Let one of the parts be x. then the other part is 4500-x. now, according go the question,

(9×x×1)/100=(15×1×(4500-x))/100

9x=15×4500-15x

24x=4500×15

x=(4500×15)/24

x=2812.5

4500-x=1687.5

Thus the two parts are 2812.5 and 1687.5
