An amount of ₹8000 is divided into two parts. The first part is lent at 5% simple interest and the second at 8% simple interest. If the total annual interest earned is ₹520, find the sum lent at 5%.
- ₹ 4500
- ₹ 3500
- ₹ 4000
- ₹ 5000
Correct answer: ₹ 4000
Solution
Let the sum lent at 5% be $x$. Then the remaining $8000-x$ is lent at 8%, and the total interest for one year is $0.05x+0.08(8000-x)=520$. Solving gives $x=4000$.
