    When an amount was distributed among 12 boys, each of them got Rs. 80 more than the amount received by each boy when the same amount is distributed equally among 16 boys. What was the amount?

    A)  Rs 3800                       

    B)  Rs 3860

    C)  Rs 3840         

    D)  Rs 3850

    Correct Answer: C

    Solution :

    (c): Let the total amount be x. Then, \[\frac{x}{12}-\frac{x}{16}=80\] \[\Rightarrow \frac{x}{48}=80\] \[\Rightarrow x=3840\] Hence total amount = Rs. 3840
