Solved Examples
1. Find the total worth of Ram’s ASSETS.
The statement I: A compound interest at 10% on his assets, followed by a tax of 4% on the interest, fetches Ram Rs. 1500 this year.
Statement II: The interest is compounded once every four months.
So, as per the data are given to us in this question, we need to find the total worth of Ram’s assets and for that two statements are given to us. We will start solving the question using statements alone and if we are not able to find the answer then we will solve the question using both the statements.
Using statement I, we can see that the compound interest i.e. 10% is given to us. Than 4% interest on this compound interest is also given to us. And this interest will be a total of Rs. 1500. But to calculate the total worth we need to have a duration of the compound interest as well as total amount or the principal amount given to us. This data cannot be found in statement I. Thus, a statement I is insufficient to determine the answer.
In statement II only the duration on which compound interest can be calculated is given to us. But there is no other information or data given which can be useful to find the answer. Thus, statement II is also insufficient to determine the answer. So, both the statements alone cannot determine the answer. But when you combine statement I and II than you can see that all the information is given to us and you can determine the total worth of Ram’s assets. So, the correct answer is option C.
