Correct answer is: Rs.1,575

Explanation:

Commission on 1 calculator

\(=\Large \frac{250 \times 20}{100} = \text{ Rs 50}\)

Commission on 1 pen

\(=\Large \frac{50 \times 10}{100} = \text{Rs 5}\)

Therefore, Required amount of commission

\(=\text{Rs }\Large 3 \left(10 \times 5 + 5 \times 5\right)\)

= Rs.1575
