Question 108

A sum of Rs16800 is divided into two parts. One part is lent at the simple interest of 6% per annum and the other at 8% per annum. After 2 years total sum received is Rs19000. The sum lent at 6% of simple interest is

Solution

Let x be the amount lent for 6%
16800 - x is the amount lent for 8%
$$\frac{2x6}{100}$$ + $$\frac{2(16800-x)8}{100}$$ + 16800 = 19000
x = 12200
