RS Aggarwal Solutions Class 8 Ex 11A

RS Aggarwal Class 8 Maths Exercise 11A is about compound interest. Compound interest is the method of addition of interest to the principal sum of money borrowed, i.e. loans or any credit deposit. It results from reinvestment of interests despite paying it out to the creditor or the lender. In this case, the amount of the previous year, which is calculated by adding principal and interest of the previous year, becomes the principal for the next year.

By practising Rs Aggarwal Class 8 Maths Chapter 11 exercise 11A, students also get to know about the compounding frequency which is considered as the number of times the interest which is accumulated is paid out each year. The frequency, in general, can be yearly, half-yearly, quarterly, monthly, weekly, daily or continuously as per the need of the question the student is attending.

Students find RS Aggarwal Maths Class 8 Exercise 11A difficult as it is based on the compound interest, which has a lot of difficult calculations. The method and formula of compound interest are quite difficult and challenging. Therefore, in order to make this Exercise more manageable and less challenging, the students should use RS Aggarwal solutions Class 8 Maths Ex 11A. The solutions here are given in a well-structured manner so that weak students can understand the methods of compound interest easily and simply. To understand the method here are some examples:-

1. Calculate Compound Interest When

Principal - 10000

Rate of interest - 10%

Time - 2years

Ans

For the first year

P - 10000

R - 10%

T - 1

I = (PRT) / 100 = (10000*10*1) / 100 = 1000

Amount = P + I = 10000 + 1000 = 11000

For the second year

P - 11000

R - 10%

T - 1

I = (PRT) / 100 = (11000*10*1) / 100 = 1100

Amount = P + I = 11000 + 1100 = 12100

Compound Interest = 1000 + 1100 = 2100

2. Calculate Compound Interest When:

Principal - 20000

Rate of interest - 20%

Time - 2 years

Ans

For the first year

P - 20000

R - 20%

T - 1

I = (PRT) / 100 = (20000*20*1) / 100 = 4000

Amount = P + I = 20000 + 4000 = 24000

For the second year

P - 24000

R - 20%

T - 1

I = (PRT) / 100 = (24000*20*1) / 100 = 4800

Amount = P + I = 24000 + 4800 = 28800

Compound Interest = 4000 + 4800 = 8800
