Answer 1

Dear student
$$\begin{gathered} \mathrm{Given} \\ \mathrm{P}=630 \\ \mathrm{I}=126 \\ \mathrm{T}=4 \\ \mathrm{We}\mathrm{know}\mathrm{that} \\ \frac{\mathrm{PRT}}{100}=\mathrm{I} \\ \Rightarrow \mathrm{R}=\frac{\mathrm{I}\times 100}{\mathrm{P}\times \mathrm{T}}=\frac{126\times 100}{630\times 4}=5\% \end{gathered}$$
