FAQs on RS Aggarwal Class 7 Solutions Chapter-12 Simple Interest
1. Explain the first type of problem that students encounter in chapter 12 Simple Interest of class 7 Maths.
The first type of Question in the 12 A exercise are questions in which the students have to calculate the payable amount on a specific time and rate of interest.
Example problem:
Mr K takes a loan from a bank for Rs 10,000, which lends the money at a 10% rate of interest. What is the total amount due on Mr K to the bank after 5 years:
To get the total amount due on Mr K, let us first calculate the Simple Interest which is,
\[\mathrm{S.I = \frac{P\times R\times T}{100} = \frac{10000\times 10\times 5}{100} = 5000}\]
Total Amount payable after 5 years = P + S.I = 20,000 + 5,000 = 25,000
