SP of the notebook = Rs. 457
Therefore, Commission on one notebook = Rs. \( \Large \frac{4 \times 457}{100} \)
and commission on 10 notebooks
= \( \Large \frac{10 \times 4 \times 457}{100} \) = Rs.18280
Now, SP of the pencil box = Rs.80
Therefore, Commission on 1 pencil box = Rs. \( \Large \frac{80 \times 20}{100} \)
Commission on 6 pencil boxes = \( \Large \frac{80 \times 20 \times 6}{100} \) = Rs.96
Hence, total commission of 1 day
= \( \Large \left(182.80+96\right) \) = Rs.278.80
Thus, total commission of 2 weeks
= \( \Large 278.80 \times 14 \) = Rs.3903.20
