How much e-waste does ABC's factory process each week?

• A. 50 tonnes
• B. 75 tonnes
• C. 100 tonnes
• D. 200 tonnes

Answer: (C)

The main idea here is to convert the weekly output into the amount that becomes e-waste by using the given waste rate. You take the total amount the factory produces in a week and apply the proportion that ends up as e-waste. E-waste = weekly production × e-waste rate.

If the case states, for example, that weekly production is 5,000 tonnes and 2% of that production becomes e-waste, the calculation gives 5,000 × 0.02 = 100 tonnes. That multiplication directly yields the weekly e-waste, which matches the correct answer.

So, the right choice reflects the data in the scenario—weekly production and the e-waste fraction—combined to give 100 tonnes. The other numbers would require different weekly production totals or waste fractions not supported by the provided data.
