    Rs. 6500 were divided equally among a certain number of persons. Had there been 15 more persons each would have got Rs. 30 less. Find the original number of persons.

    A)  45                   

    B)  50      

    C)  55                   

    D)  48

    Correct Answer: B

    Solution :

    [b] Let the original number of persons be x. Then, \[\frac{6500}{x}=\frac{6500}{x+15}+30\] or \[\frac{6500}{x}=\frac{6500+30x+450}{x+15}\] or \[{{x}^{2}}+15x-3250=0\] or x = 50
