The number of girls in the Science stream is what percentage of the number of boys in the Arts stream?
Answer: A
First, we need to find the specific numbers from the caselet data.
Number of girls in Science = 30% of 900 = 0.30 * 900 = 270.
Number of boys in Arts = 60% of 750 = 0.60 * 750 = 450.
Required Percentage = \(\frac{\text{Girls in Science}}{\text{Boys in Arts}} \times 100\)
= \(\frac{270}{450} \times 100 = \frac{3}{5} \times 100 = 60\)%.
