    Salaries of Ranjit and Sudha are in the ratio 3:4. If the salary of each in increased by Rs.6000, the new ratio becomes \[15:19.\] What is the Sudha?s present salary?

    A)  35000             

    B)  40000

    C)  30000          

    D)       36000

    Correct Answer: C

    Solution :

       Let the original salaries of Ranjit and Sudha be Rs.3x and Rs.4x respectively. Then, \[\frac{3x+6000}{4x+6000}=\frac{15}{19}\] \[19(3x+6000)=15(4x+6000)\] \[57x\,+114000=60x+90000\] \[114000-90000=60x-3x\]                                 \[3x=24000\] Shudha 's present salary =\[(3x=6000)\] \[=Rs.(24000+6000)=Rs.30000\]
