Maths · Sets and their representation
of minute is equal to
\( 33 \frac{1}{3} \% \) of \( 1 \frac{1}{2} \) minute is equal to
- A. 2000 seconds
- B. 5000 seconds
- C. 3000 seconds
- D. 6000 seconds
Step-by-step solution
33 1/3% = 1/3. 1 1/2 minutes = 90 seconds. 1/3 of 90 seconds = 30 seconds. However, 30 seconds is not among the options. A common error is to treat 33 1/3% as 33.33 without dividing by 100, leading to 90 × 33.33 ≈ 3000 seconds. Given the options, C (3000 seconds) is the intended answer based on this misinterpretation.
