Question

a bank has sum of rs.12000 invested at 10000 for 4 years to find the rate of interest

Answer 1

Answer:

Step-by-step explanation:If P denotes the principal ($), R denotes the rate (percentage p.a.) and T denotes time (years), then:-

S.I = (P × R × T)/100

R = (S.I × 100)/(P × T)  

P = (S.I × 100)/(R × T)

T = (S.I × 100)/(P × R)

If the denotes the amount, then A = P + S.I
