    A milkman sold two of his buffaloes for Rs. 20000 each. On one he made a gain of 5% and on the other a loss of 10%. Find his overall gain or loss.

    A)  Loss of Rs. 1269.84

    B)  Gain of Rs. 4268.84

    C)  Gain of Rs. 1269.84

    D)  Loss of Rs. 1200

    Correct Answer: A

    Solution :

    S.P. of 1st buffalo = Rs. 20000 Gain% = 5% \[\therefore \] C.P.\[=\frac{100\times 20000}{105}=Rs.19047.62\] S.P. of 2nd buffalo = Rs. 20000 and loss% = 10% \[\therefore C.P=\frac{100\times 20000}{90}=Rs.22222.22\] Total C.P.\[\text{=Rs}\text{. (19047}\text{.62 + 22222}\text{.22)}\] \[\text{=Rs}\text{. 41269}\text{.84}\] \[\text{Total S}\text{.P, =Rs}\text{. 40000}\] \[\therefore \] Loss = C.P.-S.P. \[\text{=Rs}\text{. (41269}\text{.84 - 40000) =Rs}\text{. 1269}\text{.84}\]
