    60 is divided into two parts such that the sum of their reciprocals is \[\frac{3}{25}\]. What is the value of larger number?

    A)  10                               

    B)  50  

    C)  25                               

    D)  20

    Correct Answer: B

    Solution :

     (b): Let part be x, 60-x \[\frac{1}{x}+\frac{1}{60-x}=\frac{3}{25}\] Take LCM to get quadratic; solving we get x = 10             \[\therefore 60-x=50\]= larger no.
