SimpleInterest Basics and Problem Solving
Simple Interest Basics and the Problem Solving mechanisms are mentioned below. All Students who are preparing for the Govt Exams or Any other exams it will be helpful.About Simple-Interest Basics and problem Solving :
Formula:
Simple Interest (S.I)= PTR/100;
where P= Principle , T=Time , R= Rate Of Intrest these are the terms used in the problem solving mechanisms
- I=PTR/100,
- P=100*I/TR
- T=100*I/PR
- R= 100*I/PT
1) Find the simple Interest on 6,000 for 4 years at 15% Per Anum ?
A) our Formula is I=PTR/100,
I=6,000*4*15/100;
I=3,600.
2) On what sum of money will the Simple-Interest be 2,000 in 5 Years at 8% per Annum?
A) Interest is 2,000 time= 5 years Rate of Interest = 8%
I=TR%
I=5*8%;
I= 40%
for 40 %---------> 2,000
100%---------> ?
100/40 * 2,000= 5,000(Answer)
3) The Simple Interest on 6,400 at 12 1/2% per Ann um Interest is 2,000 Find the Period?
A) Principal =6,400
Rate of Interest is 25/2;
I=2,000
TR%=1* 25/2;
6,400 * 25/2* 100 = 800
1 Year = 800
? years------> 2,000 => 2,000/800= 5/2 (2.5 years)
4) What sum will amount of Rs 1920/- in 4 Years at 15% per Annum ?
A) Principle =?;
Amount=1,920 Time = 4 Years Rate of Interest = 15% A=Principle+ Interest
Amount = 100 % + 60 %
160% -------> 1,920
100%----------> ?
100/160 * 1,920 = 1200 (Answer)
