Detailed Solution & Logic

Let the rate of interest be r% p.a.
SI of Amit = $ \frac{5400 \times r \times 4}{100} = \frac{21600r}{100} = 216r $
SI of Gopal = $ \frac{9400 \times r \times 4}{100} = \frac{37600r}{100} = 376r $
Given: Difference of SI = 480
376r - 216r = 480
160r = 480
$ r = \frac{480}{160} = 3 $
Rate of interest = 3% per annum
