    B)  15% loss

    C)  12.5% loss       

    D)  12.5% profit

    Correct Answer: C

    Solution :

    [c] Let CP = Rs. 100 \[\therefore \] Gain on \[\frac{1}{4}th\] i.e. Rs. 25 = Rs. 2.5 \[\therefore \] SP = Rs. 27.5 Loss on \[\frac{3}{4}th\] i.e. Rs. 75 = 20% of 75 = Rs. 15 \[\therefore \] Selling price (SP) = 75 ? 15 = Rs. 60 \[\therefore \] Total SP = 60 + 27.5 = 87.5 \[\therefore \] Loss = 100 ? 87.5 = Rs. 12.5 \[\therefore \] % Loss\[=\left( \frac{12.5}{100}\times 100 \right)\] % Loss = 12.5%
