    3 bananas are bought for Rs. 2 and sold at 2 bananas for Rs. 3. Find the gain percent.

    A)  100%                          

    B)  85%          

    C)  125% 

    D)  130%

    Correct Answer: C

    Solution :

    (c): C.P (one banana) = (2/3) Rs. S.P (one banana) = (3/2) Rs. \[\therefore gain%=\frac{\frac{3}{2}-\frac{2}{3}}{2/3}\times 1005\] \[=\frac{\frac{9-4}{6}}{\frac{2}{3}}\times 100%=\frac{5}{4}\times 100%=125%\].
