An amount of Rs. 2143 is split into two parts. The first part is invested @8% for 6 years, and the second @6% for 8 years. What is the ratio of the first part is to the second part if they yield the same amount of simple interest?
Let the amounts be x and y. We have x × r1 × t1 = y × r2 × t2. We can see that x : y is same as r2t2 : r1t1. The ratio is (6 × 8) : (8 × 6) = 48 : 48, or same as 1. Please note that the answer is independent of the value of the total amount.
