Question

A man invested 3500, a part of it at an annual interest rate of 12% and the rest at
14%. If after a year, he received * 450 as annual interest, how much did he invest at each
rate?​

Answer 1

Step-by-step explanation:

Let the amount invested at 14%be 100x

amount investes at 12% is (3500-100x)

invested earned= 14x+420-12x=450

2x=30

x=15

1500rs. @14%+2000rs.@12%
