    5% of income of A is equal to 15% of income of B and 10% of income of B is equal to 20% of income of C. If the income of C is Rs. 2000, what is the total income of A, B and C?

    A) Rs. 14000

    B) Rs. 16000

    C) Rs. 18000

    D) Rs. 12400

    Correct Answer: C

    Solution :

    [c] \[\frac{10}{100}\times B=\frac{20}{100}\times C\] \[\Rightarrow \]   \[B=2C\] \[\Rightarrow \]   \[B=(2\times 2000)=\text{Rs}.4000\] \[\frac{5}{100}\times A=\frac{15}{100}\times B\]             \[\Rightarrow \]   \[A=3B=(3\times 4000)=\text{Rs}.12000\]             \[\therefore \]      \[(A+B+C)\]             \[=\text{Rs}.\,\,(12000+4000+2000)\]             \[=\text{Rs}\text{.}\,\,18000.\]
