Answers
Answer:
It is given that,
1) principal, p=Rs 2000
Rate of interest, R=5%
Time,T=5years
Simple interest ,
S.I=PRT/100=2000×5×5/100
S.I=Rs 500
2)P=500, R=12.5%
T=4 years
S.I=500×12.5×4/100=Rs.250
3)P=4500, R=4%
T=6 months=1/2 year
S.I=4500×4×1/2/100=Rs.90
4) P=12000, R=18%
T=4 months=1/3 year
S.I=12000×18×1/3/100=Rs 720
5)P=1000, R=10%
T=73 days=73/365 year=1/5 year
S.I=1000×10×1/5/100=Rs.20
Step-by-step explanation:
Hope it helps you.......
Concept:
If you know the principal amount, the rate of interest, and the time periods, you can use the simple interest formula to calculate the interest.
The following is a simple interest formula:
SI = P X R X T /100
SI stands for simple interest.
Principal (P)
interest rate, or R (in percentage)
T is the time period (in years)
The following formula is used to determine the overall sum:
Sum (A) = Principal (P)+ Interest (I)
Where,
The entire amount repaid at the conclusion of the borrowing period is indicated by the letter (A).
You can also write the total amount formula for simple interest as follows:
A = P(1 + RT)
Here,
A = The overall sum as of the specified time.
P stands for the loan's initial principal amount.
R is the interest rate (per annum)
T is the taken taken in years
Given:
(i) Principal = Rs 2000, Rate of Interest = 5% per annum and Time = 5 years.
(ii) Principal = Rs 500, Rate of Interest = 12.5% per annum and Time = 4 years.
(iii) Principal = Rs 4500, Rate of Interest = 4% per annum and Time = 6 months.
(iv) Principal = Rs 12000, Rate of Interest = 18% per annum and Time = 4 months.
(v) Principal = Rs 1000, Rate of Interest = 10% per annum and Time = 73 days.
Find:
Find the simple interst for each of the following cases
Solution:
1) principal, p=Rs 2000
Rate of interest, R=5%
Time,T=5years
Simple interest ,
S.I=PRT/100=2000×5×5/100
S.I=Rs 500
2)P=500, R=12.5%
T=4 years
S.I=500×12.5×4/100=Rs.250
3)P=4500, R=4%
T=6 months=1/2 year
S.I=4500×4×1/2/100=Rs.90
4) P=12000, R=18%
T=4 months=1/3 year
S.I=12000×18×1/3/100=Rs 720
5)P=1000, R=10%
T=73 days=73/365 year=1/5 year
S.I=1000×10×1/5/100=Rs.20
Therefore, the simple interest for the question 1,2,3,4,5 is Rs 500.Rs 250,Rs 90,Rs 720,Rs 20
