    Section A
    School B
     

    The total expenditure of School B is Rs.12 lakh and the number of non-teaching staff is 50. If 30% of the non- teaching staff are removed, then the total expenditure reduces by what per cent?

    A)  12%                

    B)  4%   

    C)  6%                  

    D)  8%   

    E)  13%

    Correct Answer: C

    Solution :

    In School B, the expenditure on non-teaching staff \[=12\times \frac{20}{100}=2.4\,\text{lakh}\] Expenditure on each non-teaching staff\[=\frac{240000}{50}\]=Rs. 4800 After removing 30% the number of non-teaching staff \[=50\times \frac{70}{100}=35\] Salary of 35 non-teaching staff\[=35\times 4800=\]Rs. 168000 =1.68 lakh \[\therefore \]Reduction in expenditure =2.4 lakh - 1.68 lakh =0.72 lakh = Rs.72000 \[\therefore \]Percentage reduction in total expenditure \[=\frac{7200}{1200000}\times 100=6%\]
