    A shopkeeper sells notebooks at the rate of Rs. 457 each and earns a commission of 4%. He also sells pencil boxes at the rate of Rs. 80 each and earns a commission of 20%. How much amount of commission will he earn in two weeks, if he sells 10 notebooks and 6 pencil boxes a day?

    A) Rs. 3903.20

    B) Rs. 1586

    C) Rs. 1496

    D) Rs. 1596

    Correct Answer: A

    Solution :

    [a] \[\because \]SP of the notebook = Rs. 457 \[\therefore \] Commission on one notebook             \[=\text{Rs}\text{.}\frac{4\times 457}{100}\] and commission on 10 notebooks             \[=\frac{10\times 4\times 457}{100}=\text{Rs}.\,\,182.80\] Now, SP of the pencil box = Rs. 80 \[\therefore \] Commission on 1 pencil box             \[=\text{Rs}.\,\,\frac{80\times 20}{100}\] Commission on 6 pencil boxes             \[=\frac{80\times 20\times 6}{100}=\text{Rs}.\,\,96\] Hence, total commission of 1 day \[=(182.80+96)\] = Rs. 278.80 Thus, total commission of 2 weeks \[=27830\times 14\] = Rs. 3903.20
