    A person sells 36 oranges per rupee and incurs a loss of 4%. Find how many oranges per rupee to be sold to have a gain of 8%?

    A) 32            

    B) 30

    C) 28                         

    D) 34

    Correct Answer: A

    Solution :

    We have \[=\frac{100+500}{20}=\frac{600}{20}=30s.\] \[=\frac{500}{20}25\] \[=\left( \frac{x+y}{u-v} \right)\] \[=(u-v)km/h(u>v)\] \[=(u+v)km/h.\] He has to sell 32 oranges per rupee.
