Simple Interest $\left(\mathit{S}\mathit{I}\right)=($ Principal × Rate × Time $)∕100$
Calculation:
Let the rate of interest be $\mathit{R}\%$.
Interest for Amit $=\left(5400\times \mathit{R}\times 6\right)∕100$
Interest for Gopal $=\left(9400\times \mathit{R}\times 6\right)∕100$
Difference in interest $=$ Interest for Gopal - Interest for Amit
$\Rightarrow$ ₹ $960=\left[\left(9400\times \mathit{R}\times 6\right)∕100\right]-\left[\left(5400\times \mathit{R}\times 6\right)∕100\right]$
$\Rightarrow$ ₹960 $=\left[\left(9400-5400\right)\times \mathit{R}\times 6\right]∕100$
$\Rightarrow$ ₹960 $=\left[\left(4000\times \mathit{R}\times 6\right)∕100\right]$
$\Rightarrow \mathit{₹}960\times 100=4000\times \mathit{R}\times 6$
$\Rightarrow 96000=24000\times \mathit{R}$
$\Rightarrow \mathit{R}=96000∕24000$
$\Rightarrow \mathit{R}=4$
