    From the salary of an officer, 10% is deducted as house rent, 15% of the rest he spends on children's education and 10% of the balance, he spends on clothes. Then he is left with him Rs. 4131. Find his total salary.

    A)  Rs. 8000          

    B)  Rs. 7000

    C)  Rs. 7500          

    D)  Rs. 6000

    Correct Answer: D

    Solution :

    Total salary = Rs. x, then \[x\times \frac{100-10}{100}\times \frac{100-15}{100}\times \frac{100-10}{100}=4131\] \[\therefore \]\[x=\frac{4131\times 100\times 100\times 100}{90\times 85\times 90}=\,\,Rs.\,\,6000\]
