Question
The S.I. on a Sum of money will be Rs.600 after 10 years. If the Principal is tripled after 5 years, what will be the total interest at the end of 10th year?
Solution
To solve this problem, we need to understand the concept of Simple Interest (S.I.). The formula for Simple Interest is I = PRT/100, where P is the principal amount, R is the rate of interest, and T is the time in years.
Given in the problem, the S.I. on a sum of money will be Rs.600 after 10 years. This means that the interest for the first 5 years is Rs.300 (since the interest is the same for each year).
Now, the principal is tripled after 5 years. So, the interest for the next 5 years will be 3 times the interest of the first 5 years, which is 3*300 = Rs.900.
Therefore, the total interest at the end of the 10th year will be the sum of the interest for the first 5 years and the interest for the next 5 years, which is 300 + 900 = Rs.1200.
