find simple intest
by solving
Answers
Step-by-step explanation:
Solution :-
1)
Principle (P) = Rs. 12000
Time (T) = 2 years 8 months
=> T = 24+8 months
Since 1 year = 12 months
=> T = 32 months
=> T = 32/12 years
=> T = 8/3 years
Rate of interest (R) = 5%
We know that
Simple Interest = PTR/100
=> SI = (12000×8×5)/(100×3)
=> SI = 480000/300
=> SI = 1600
Simple Interest = Rs. 1600
2)
Principle (P) = Rs. 8000
Time (T) = 1 3/4 years
=> T = 7/4 years
Rate of interest (R) = 6%
We know that
Simple Interest = PTR/100
=> SI = (8000×7×6)/(100×4)
=> SI = 336000/400
=> SI = 3360/4
=> SI = 840
Simple Interest = Rs. 840
3)
Principle (P) = Rs. 15000
Time (T) = 73 days
1 year = 365 days
=> T = 73/365 years
Rate of interest (R) = 10%
We know that
Simple Interest = PTR/100
=> SI = (15000×73×10)/(100×365)
=> SI = 10950000/36500
=> SI = 109500/365
=> SI = 300
Simple Interest = Rs. 300
Answer :-
1) Simple Interest is Rs. 1600
2) Simple Interest is Rs. 840
3) Simple Interest is Rs. 300
Used formulae:-
→ Simple Interest = PTR/100
- P = Principle
- T = Time
- R = Rate of Interest
