P is the principle, R% is rate and time period is T, Simple Interest S and Compound Interest is C then observe the following cases. 

Here, P = 20000, A = 50000, T = 12 years(T× is time period) S.I. = A - P = 50000- 20000 = 30000 S.I. = P × R × T /...

C) Butanoic acid

A) metal piece is colder than wooden piece

D) Compound microscope

C) Pascal’s principle

Correct option is   C) \(\frac{PTR}{100}\)

Correct option is (A) 8 Let the amount taken be Rs P. \(\therefore\) S.I. = \(\frac{16}{25}\times\) P = \(\frac{16P}{25}\) R = T \(\therefore\) S.I. = \(\frac{PRT}{100}\) \(\Rightarrow\) \(\frac{16P}{25}\) = \(\frac{P\times R\times R}{100}\)  \((\because\)  R = T) \(\Rightarrow\) \(R^2=\) \(\frac{16P}{25}\times\frac{100}P\) \(=16\times4=64=8^2\) \(\Rightarrow\) R = 8 \(\Rightarrow\) T = R = 8
