    D)  Rs.3789.47     

    E)  Rs.2312.91

    Correct Answer: C

    Solution :

    Salary of all the teachers in School A \[=1000000\times \frac{30}{100}=\]Rs. 300000 Number of new teachers \[=60\times \frac{30}{100}=18\] Number of new teachers \[=(60-18)=42\] Number of old teachers = (60 - 18) = 42 Let the salary of an old teacher be Rs.\[x.\] \[\therefore \]Salary of a new teacher \[\frac{x\times 60}{100}=\frac{3x}{5}\] Now, salary of Principal =Rs.\[\frac{11x}{10}\] So, \[x\times 41+\frac{11x}{10}+\frac{3x\times 18}{5}=300000\] or, \[\frac{410x+11x+54x}{10}=300000\] or, \[475x=300000\times 10\] \[\therefore \]\[x=\frac{300000\times 10}{475}=\]Rs. 6315.78 Salary of a new teacher \[=6315.78\text{ }x\text{ }-=3789.47\]
