In how much time will the simple interest on Rs.2,000 at the rate of 8 % p.a. be the same as the simple interest on Rs.4,000 at the rate of 12 % p.a. for 3 years ?
Answers
Answer:
Rs. 20
Step-by-step explanation:
Principal (P) = Rs 2000
Rate of interest (R) = 5% p.a.
Time (T) = 5 years
Simple interest = P×R×T100=2000×5×5100=Rs 500
(ii) Principal (P) = Rs 500
Rate of interest (R) = 12.5% p.a.
Time (T) = 4 years
Simple interest = P×R×T100=500×12.5×4100=Rs 250
(iii) Principal (P) = Rs 4500
Rate of interest (R) = 4% p.a.
Time (T) = 6 months
T =612=12 year (1 year = 12 months)
Simple interest = P×R×T100=4500×4×12100=4500×4×1100×2=Rs 90
(iv) Principal (P) = Rs 12000
Rate of interest (R) = 18% p.a.
Time (T) = 4 months =412=13year (1 year = 12 months)
Simple interest = P×R×T100=12000×18×1100×3=Rs 720
(v) Principal (P) = Rs 1000
Rate of interest (R) = 10% p.a.
Time (T) = 73 days = 73365 year (1 year = 365 days)
Simple interest = P×R×T100=1000×10×73100×365=Rs 20
