    Question

    A person who spends 55% of his monthly income is able to save ₹6,408 per month. His monthly expenses (in ₹) are:

    A.

    7,832

    B.

    7,834

    C.

    7,873

    D.

    7,843

    Correct option is A

    Given: 

    Expenditure = 55% of monthly salary 

    Saving = ₹6,408 per month

    Formula Used: 

    Income = Expenditure + Saving 

    Solution: 

    Expenditure is 55% of income,

    then, Saving = 45% of income 

    Now, 

    45% of income =  ₹6,408 

    Income = 640845×100=14240\frac{6408}{45}\times 100 = ₹14240 

    Monthly expense = 14240×55100=783214240 \times \frac{55}{100} = ₹7832​​
