    A) 25%                 

    B) 30%   

    C) 32%     

    D)        40%

    Correct Answer: C

    Solution :

    Sol. [c]
    Let total salary = 100
    Savings = 10% of 100 = 10
    Expenditure = 90% of 100 = 90
    Now new expenditure
    \[=90\times \frac{130}{100}\,=117\]
    New savings \[=10\times \frac{150}{100}\,=15\]
    New salary = 117 + 15 = 132
    % increase in salary
    \[=\,\frac{132-100}{100}100\]
    \[=\frac{32}{100}\,\times 100\]=32%
