    A) 7%      

    B) 21%

    C) 28%    

    D) 35%

    Correct Answer: C

    Solution :

    [c] Original savings \[=\,\,Rs.(13500-9000)=Rs.4500\]
    New income \[=114%\] of Rs. 13500
    \[=Rs.(114\times 135)=Rs.15390\]
    New expenditure \[=107%\] of Rs. 9000
                            \[=Rs.(107\times 90)=Rs.9630\]
    New savings \[=\,\,Rs.\,\,(15390-9630)=Rs.\,5760\]
    \[\therefore \]      Percentage increase in savings
        \[=\,\,\,\frac{5760-4500}{4500}\times 100=\,\,\,\frac{1260}{45}=28\]%
