Question

Rs 350 become rs 400 at certain simple interest in 2 years .if rate of interest is 2 percent less then what will be the amount after 4 years?​

Answer 1

Answer:

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
