(A) Let the rate of interest be $r \%$. The formula for simple interest is $SI = \frac{P \times R \times T}{100}$. Interest from $B = \frac{10000 \times r \times 3}{100} = 300r$. Interest from $C = \frac{6000 \times r \times 4}{100} = 240r$. Total interest received is $5400$. Therefore,$300r + 240r = 5400$. $540r = 5400$. $r = \frac{5400}{540} = 10 \%$. Thus,the rate of interest is $10 \%$.
