Answer:

Correct Answer: E

Solution:

  • SP of notebooks $ =Rs\text{. 457} $

$ \therefore $ Commission on one notebook $ =Rs.\frac{4\times 457}{100} $ and commission on 10 notebooks $ =\frac{4\times 457}{100}\times 10=Rs\text{.},182\text{.80} $ SP of pencil box = 80 Commission of one pencil box $ =\frac{80\times 20}{100} $

$ \therefore $ Commission of 6 pencil boxes $ =\frac{80\times 20}{100}\times 6=96 $ Total commission in one day = 182.80 + 96 $ =Rs.278.80 $

$ \therefore $ Total commission in 14 days $ =278.80\times 14 $ $ =Rs.3903.2 $
